Electricity is technology. Why is there different standards

Also, can't we just use 1 standard plug type for the world?

There's no significant differences.
And why there's a difference, the US went to build an electrical grid first and ended up with a slightly inferior infrastructure, and replacing it now would cost an extreme amount of money that makes the US' military budget look like a toy.

>>52270885
>Why is there different standards for electricity voltages and frequencies?
Because the spread of these was generally limited to before the era of instantaneous, immediate communication and co-operation, on a mostly ad-hoc basis.

There's no real need to do anything about it, either, given that adapters are simple, known technology; and with the advent of globalisation you can generally get anything you need locally anyway.

>>52270897
>can't we just use 1 standard plug type for the world?
well USB is a thing that's useful and a global standard. pipe whatever goofy format you want into your house, and leave the rest to the USB cable and socket.

...that's assuming you buy proper, in-spec USB equipment (ie anything not from the back of a Chinese flea market, bundled along with SUPAR MARIO WORLD 300 for the Chindento RS video game entertainment systam!!).

120v requires thicker wiring to transfer the same amount of watts. It is also generally safer for electricians to work with because your body's electrical resistance is able to keep the amperage low enough to prevent your heart from being kill.

240v requires thinner wiring to transfer the same amount of watts. It is also generally more dangerous for electricians to work with because your body's electrical resistance is less able to keep the amperage low enough to prevent your heart from being kill.

It's important to remember that while the amps is what ultimately kills you, the voltage influences how "easy" it is to kill you. This is why a 2 amp phone charger won't kill you. The higher the voltage, the less electrical resistance your body will have to the current.

Finally while US homes typically use 120v for almost everything, they can use 240v (ac units, electric stoves) by using two 120v nerves.

240v x 10 amps = 2,400 watts

120v x 20 amps = 2,400 watts

Only if it's grounded, not all of them are.

US likes to use their own standards, regardless of what is best.
And for plugs, is is not a problem as most of europe is compatible and the main difference is how ground is connected and this makes the plugs look different.
Denmark has the prettiest plugs, Germany has the safest plugs and Switzerland has the smallest ones.

As for frequencies, that has the least impact of them all but it is easier to collaborate with other countries if they use a compatible power grid.

Honestly though. From a safety standpoint, the Britbong plug and socket are ideal. The only real argument that can be made against them is their size.

>>52271546
Yeah, but your breaker needs more amps then.
Then you get a situation where you wanna use your welder and suddenly you need 100 amp breakers because of the low voltage.
Suddenly having 0.20% chance of surving against 0.30% doesn't seem very important.

Here in the Netherlands we'll soon have to pay taxes over the electricity we generate during the day and deliver to the grid, and then pay taxes again in the evening to use the same amount of electricity.

That's why batteries will become necessary.

And converting battery power to high voltage alternating current only to convert it back to low voltage direct current a few meters down the wire is retarded.

Well as you can see there is to ways to use electricity - productive (220v/50hz) and secure (120v/60hz). 220/50 more economic type of transfering energy (about double less loses then 120), also 50 hz is more dangerous to human body

>>52272260
120V and 240V are only used between the house and the transformer a few meters away, the losses with either are pretty minimal.

>>52272243
Higher voltage has lower power loss over distance.

>>52272243
Not even down the street.

And that's my point: there is no good reason other than "we happen to have these 240V AC sockets"

Just add DC wiring to your home, and USB sockets to connect to it.

>>52271546

I think what he meant was that 240v will break through your skin's natural resistance easier, there are less altering factors required.

Not entirely true, kitchens usually have their own circuit (at least if you want electrical ovens etc.).

Anyway, whilst it's very annoying on old houses that need rewiring, circuit breakers make diagnosing issues fairly easy.

Why do we have these threads?
They usually end up being pointless nationalism, and for what?

Any device made since forever that is worth taking overseas usually works with any combination of 230/110v and 50/60hz. If you are going overseas, it doesn't hurt to take an adapter either.

You'd have to be a special type of autistic to take a toaster or iron (two of a small minority of devices that aren't multispec in my house) on holiday or a business trip overseas.

I've got a shoebox of three different adapters from my travels. One for Yankee, Euro and British standards. When I go overseas, I bring the most relevant. Each cost me about five australian dollars.
Now compare that to the cost of retrofitting an entire nation of devices for an international standard plug. It'd be even more expensive to change frequencies and voltages (frequency would be a big killer for industry --to the point where the japs keep both for different regions).

>Why is there different standards for electricity voltages and frequencies? Is there any significant differences?
Yes. Transmission losses and the amount of power you can deliver by a cable of size xy are different.

>>52270897
Because nationalism and unwillingness to do large projects like this.

The EU thought about going with IEC 60906-1 ( https://www.wikipedia.org/wiki/IEC_60906-1 ) -which is the current obvious gold standard for plugs, an excellent design.

But then they went "herp" over having to pay for this transition, and how it would be oh-so problematic for their current governments to do this transition rather than the great other things they've allegedly planned.

And if the EU can't do it, someone else has to do it first, or it won't happen.

First you use your finger to orientate the plug in your mind and in your hand.

>>52273283
We have two pins like that in South Africa, usually for lower power devices. I don't know why you would be messing with plugs in the dark so that's not really a problem. One advantage of the three pin plugs is that they're secure, it's pretty much impossible to remove them accidentally.

>>52273504
Then you use your finger to do the same with the power point.
Most have an identifying simple for the earth.

It's particularly hard with power boards. Our power points must be the right way up by law, so they aren't nearly as hard.

It greatly depends if you're wearing shoes or not, and what type of floor you're on.

As a kid I got big shocks from a faulty dishwasher a couple of times, as I would walk barefoot on the tiled kitchen floor.
While my mom wearing shoes with rubber soles didn't feel a thing.

Still, even in the worst case scenario it won't kill you just trip the circuit breaker - that's what they are for.

>>52273557
Why the fuck is there a switch?

>>52273456

If the source is 3 phase, doesn't that mean any 220v appliances will get 2 phases? Pretty much every house here in America has at least 2 or 3 220v outlets.

>>52273557
Then ensuring the switch is off, you make the two meet. You will usually keep your finger in a position to contact both the prongs and the socket as to assist you with the complex aligning process.

It's safer than you think, the power point has no power when the switch is off so it's safe to touch.

>>52273596
Why the fuck don't you have them?

It prevents arcing on the contacts, makes sockets a fuckload safer for kiddies, allows you to turn things off at the mains (like a toaster) without having to plug it out (great for plugs in awkward positions).

>>52271495
just because sockets have a ground connector doesn't mean there is anything plugged to it/ many old houses do not have ground cabling and use sockets with ground connector

>>52273653

>>52273617
>If the source is 3 phase, doesn't that mean any 220v appliances will get 2 phases?

No.
You get one phase and neutral.

>>52273617
Single phase, it's two opposing sides of the same transformer essentially, one side pushes and the other side pulls. Three phase is three completely separate transformers/lines.

>>52273620
>keep your finger in a position to contact both the prongs and the socket as to assist you with the complex aligning process.

Oh wow.

I'm so glad we have recessed sockets.
Just jam it in there and turn it a little until it aligns.

True.

Fairly sure that's illegal here.
In any case it's retarded, just use the cheaper non-grounded sockets.

>>52273556
South Africa also has IEC 60906-1. It's the only country that uses exactly this gloriously well-designed standard.

I compliment you for that. Just... it's unfortunately not your only standard.

>one side pushes and the other side pulls.

No it doesn't.

One side alternatively pushes and pulls.
The other side doesn't do anything, and is (in theory) safe to touch.

You're describing one phase and a neutral wire. America has split single phase.

>>52273823
Lol, yeah. No idea what's going on with that. My parents built a house a year ago, and there wasn't any requirement to use the new standard (didn't even know about it). I've only ever seen the new socket once, at some random mall food court.

HOW TF YOU EXPECT TO USE FUSES NIGGA

>>52273123
>who needs 3 phases
a lot of people.
If you have a vacation house and you want to heat it, you can do it a lot faster with 3 phases.
And several appliances like washing machines, dryers, ovens, etc can be a lot more efficient by using 3 phases.
And unless you live in some old city, 3 phases has been the norm for decades.

>>52272083
have fun with the almost impossible to raise the voltage of DC

>>52273902

>>52274275
because euro homes are for euro poor than cant afford a properly wired home

>>52271733
You wouldn't run a welder off of a 120V plug. The standard 120V American plug is only rated for 20A. You would run a dedicated line using a special plug and in all likelyhood it would be a 240V line. This what they do for heaters and dryers.

>>52274380
Coming from the country where most of the houses aren't built on bedrock.

>>52274428
I can run a welding machine out of a normal socket running on a 20A breaker here in Europe, 16A is already too low.

It's possible these days but HVDC still sucks for any place where disruptions in service might occur. HVDC doesn't like to be turned off, it has a tendency to arc. AC no matter the voltage always has very brief moments where it's electrically "off" which allows for it to be turned off "relatively safely" at any time.

>>52274380
Anon, Central European houses are mostly wired up with HV wires to big appliances and then "household" 230V.

>>52274275
What are you talking about?

Higher voltages like 230V are more efficient, that's actually just better.

Even power-wise:
USA: 120V, 15 Amps = 1800 watts
EU: 230V, usually 8-16 Amps = 1840-3680 watts. No, 16A isn't rare - it's quite common.

>>52275167
Every single one of my circuit breakers is 16A, there's only a single 20A in the bathroom.
It's probably cheaper than lower amp ones here for some reason.

>>52275226
To make sense of this: Are you in the USA or Europe?

>>52275445
Europe.

>>52275460
I see. Yep, 230V / 16A is common.

20A a bit less so, but you're perhaps in Germany? Then it'd also make sense why you rarely see less than 16A, either.

Still, 400V / 16A three phase (which is common for kitchens etc.) = 6400 watts is also in many places. Europe got decent household power.

>>52272383
A toaster can actually act as a controller

>>52275543
Croatia, and the only reason I have a single 20A breaker is for when I pull out a bunch of power tools outside, it's not really that hard to change the other 4 to 20A, but there's no reason.

But industry, science, and international government bodies use them. The only ones who still keep it alive are rednecks, blacks, and lazy suburbinites.

110V = retard proof, adopted by retarded americans that couldn't keep their forks out of wall sockets.

220V = manmode, lowers installation costs.

>>52271349
>amperage
It's called current.

And also, current doesn't kill you. Current * time kills you. In other words, it's how much charge is transferred to your body.

>>52273840
Well, if they don't care and don't plug in ground, their company and them will go under and buttfucked more than young adult in prison.

>>52272748
No.
And stop calling it amperage.
>>52272704
Voltage is how much energy the electrons have. A volt is a unit of joules per coulomb (V = J/C), Joules being energy (obv) and coulomb being a number of electrons (1 coulomb roughly equalling 6.3e18 electrons).

Electrical engineers take both voltage and current into consideration for just about everything. People may talk about voltage slightly more often though because it's easier to measure and predict. Creating voltages from physical processes is relatively common and easy to do, and then you can compute how much current would flow due to ohm's law. The only physical processes that induce currents independent of voltage are photoelectric processes and magnetic fields, both of which are still used plenty.

>>52278351
lolno. You can be shocked with 0.1 milli amps of current at 10kV 24/7 and nothing would happen.

But if you got shocked with 20 amps of current at 240 volts and your body's electrical resistance only reduced the current to 500 milli amps then you are going to die whether the shock lasted 1, 2, 3, or 20 seconds.

Anyway in this regard 120 volts is pretty safe as the only way you would die from this is if you intentionally went up to the junction box and grabbed the main nerves while soaking wet.

240 volts on the other hand is lethal in less dramatic scenarios.

>>52278559
Again, current * time.

You don't have a clue how tasers work, do you?

it uses an inductor to build up a large magnetic field. When the barbs are shot out, the gun cuts off battery power to the inductor, which collapses the magnetic field. Collapsing magnetic fields can induce huge charges, which translate into high voltage and current (see: flywheel diode), but only for a very small amount of time. A taser has a 50kV potential before it hits your skin, but once it hits your skin that voltage drops like a rock.

Externally, your body can have anywhere from 150Mohms to 500Mohms of internal resistance. The barbs on a taser break your skin, however. Once your skin has been broken, there's likely around a 400 ohm resistance between the taser barbs. 50kV / 400 ohms = 125 amps.

According to your logic, you'd die instantly. This is not the case, because it happens for so little time.

>>52270885
because it would cost a shitload for somewhere to switch to a new standard

>>52278528
it's how potential energy it has you dumb. The energy it's determined by it's speed.

>>52278882
Yes, potential energy. Energy, which is measured in joules. Voltage specifically is how much energy can be extracted from a certain number of electrons. Joules per coulomb.

>>52278882
>>52278939
And the energy isn't determined by its speed, the amount of current that will flow through a constant resistance is determined by how much energy that current has (voltage).
Voltage = joules / coulomb
Current = coulombs / second
Power = V * I = joules / second

>>52270897
I've seen over the years the hate for North American sockets but I never got it. They work way better than any other I've seen here in Europe and I think they are cheaper to make too.

>>52278528
No, it is amperage.
