Can I kill myself by touching the biggest PSU capacitor? I will

It won't kill you! Will just throw you a few steps back.

I trust my experience more than CNET you know :-/

You'd need a beefier capacitor than that, like the kind in old arcade machines. Also it would throw you into cardiac arrest, which would be extremely painful until you lose consciousness.

>>57012448
You're a big guy

Capacitors only store charge, dumbass. There's no current flowing through them so they're not dangerous at all.

Even if it's a total hackjob design that doesn't have bleeder resistors across the largest caps, the answer is 'it depends'.

>>57012640

looooool

>>57012640
Until you shot then
Oh boy you're in for a shock

In order to die you need a current of around 100-200 mA. Any less than that you will only experience mild burns, any more than that and you can be resuscitated, so you must pick just the right size capacitor to touch, assuming that every other factor is constant, which it never is

>>57012309
as with all leccy, yess it can kill you, touch it with both hands and it shorts across your heart and kills you, one hand and it just hurts.

>>57012309
I once touched a big capacitor in an industrial machine by accident (was servicing the damn machine and forgot to discharge the caps) with the back of my hand (which probably saved me) and I literally jumped back two meters and fell on the floor. Came to my senses some ten seconds later, without feeling in my arm. Two more minutes to regain my arm.

Scary as fuck, I could have died there.

>>57015715
unless there is sufficient current to go through your arm, across your heart, down your legs, through your rubber shoes and ground to earth.
then you fuk'd.
Not a calculation you want to be doing really.

>>57015788
Glad you made it, hurts like fuck doesn't it.

>>57012309
No it won't kill you by just touching it, it might be really hot if it's wired in wrong or if it has too much current flowing through it, but just touching it? No.

>>57016009

Can confirm. Have touched capacitors and lived.

One man has been struck by lightning like seven times but that doesn't stop other people from dying when they are struck by lightning.

Your survival story isn't a guarantee of safety.

>>57016190
all we need now is someone to confirm they have died, I shan't hold my breath

Yes, they can kill you. It's not guaranteed since there are many factors at play like skin resistance, point of contact, the capacitor's charge at the moment, capacitance of the thing etc. but they can kill. If i suspect any leftover charge at the PSU after unplugging it, i press the power button on the PC to discharge it. Now have a video of a dude making a weapon out of a big one:

>>57016523
>i press the power button on the PC to discharge it.
Isn't there usually a resistor or LED to discharge the +5V standby line though? Pressing the power button on your computer won't do shit if you don't have +5V standby because that is what is supplying power to the PCH which will detect your button press.

>>57016523
>Yes, they can kill you.
I find that hard to believe with your puny 110V mains. Most electros I have used have insulated cases anyhow. The biggest power supply electros I work on have bare-metal cases and are clamped to the chassis.
If you get a belt from an electro it's probably faulty - on the way out.

>>57016839
>I find that hard to believe with your puny 110V mains
>voltage is important

Bridge the leads with a screwdriver, obviously one with a non-conducting handle, to discharge it.

When I rub my feet on the carpet and give you a static shock, that's thousands of volts.

You don't die, do you?

Educate yourself.

>>57017231
guess what causes current

>>57017193
Yes, I know without adequate voltage, the current won't be able to flow through you, but current is actually the killer.
But even then, even small amounts of current can kill if I goes though your heart.

itt /g/ nigger retards giving poor advice.
stick to your babyshit linux terminal please.

electricity only has two methods of killing you.
the first is by thermal. you can cook your arms and legs to a black crisp all day long but you wont die from this if you seek medical attention. however, your organs are a different story. they dont like sizziling on a frying pan. and your brain doesnt like it either. your head can cook too.
but these types of electrocution (literal executions by electricity) are highly uncommon. only lightning and high voltage power plants typicially cause these types of electrocutions. and its rare even with lightning.

the second most common method of electrocution is when electricity crosses your heart.
this is practically the only way you can die from electricity. you can be shocked by anything, so long as it doesnt cross your heart it wont kill you.

>>57017294
don't forget blood poisoning by electrolysis

>>57017255
Not voltage.

>>57017409
i am seriously retarded for falling for this bait

>>57017294

also, the voltage you receive from large capacitors in tandem depends on how the capacitors are drained.
capacitors are a dangerous type of electric storage because all the energy they store can be instantly discharged. this is unlike any other battery.

you cant really kill yourself this way, although its possible. the current would have to cross your heart but the potential in voltage is actually there.

to build a high enough voltage to potentially kill you, you would need to quickly drain them with a metal object like a screwdriver

>>57017366

who the fuck has died from this?

>>57012309
you'll be safe as long as you don't touch any of the AC parts
if you do touch anything hooked directly to mains, it's all up to luck and how well you're insulated from ground

>>57017460
Current is a result of resistance, not voltage.

>>57015664
>wordpress
>how much voltage will kill you?
nah

>>57015715
You need high enough voltage to overcome the skin's resistance, which is high, and enough total power to actually be killed.
>leccy
Go away, you stupid British faggot.

>>57017822

this is a very stupid way of looking at it.
technically anything which is not a frozen high temperature superconductor provides marginal resistance

>>57017155
You need a fairly high voltage for the current to reach all the way to your heart in the first place.

>>57017901
Which is why current is not infinite.

>>57017916
And 100V is more than enough to over come the body's resistance.

>>57018096
Show me a defib that uses only 100V

>>57018313

>>57012797
>100-200 milliamp hours
>no voltage
>fucking Mah

>>57017822
Technically they're all linked and no electricity in the world has only 2 of the 3 parameters

>>57018555
The point is though that you can have 1V at 0.001A and 1V at 1000A.

And voltage can exist without current, but in an active circuit you will have both.

well, since ((((google)))) is literally worthless for searching "electrolysis blood poisoning" (actually because you're an idiot and don't know the proper term for it) i managed to remember something on the subject myself.

there was a documentary on cops killing people with tasers.
though i don't remember if any deaths were a direct result from electrolysis or a stimulated neuro chemical effect.
if i remember correctly, people were dying because being zapped would flood their bodies with potassium- again, not sure if direct result of electrolysis or neuro chemical reaction.

now that i really think of it, it might be electrolysis, as this makes much more sense and seems very likely

No retard.
This is not the proper term for researching the effects of electrolysis on the human body

>>57017155
Actually yeah, it's the combination of both.

>>57020334
Voltage allows the current to overcome the body's resistance but thousands of volts at low current does nothing more than tickle.

Also the is the matter of just where the electrical charge touches, like how a 9V battery on your finger doesn't do anything but if you touch it to your lip or tongue you definitely feel it.

It isn't a complex relationship, when working with transport AC voltage the voltage is high enough to kill you, that's why it is the current that matters.

>>57013425
What in the world? That's a home made cap? What would you do with something like that?

>>57012448
Big guy??

>>57016085
It also depends on the capacity of the component and you would still need a good amount of amperage going through it, around 20 amps at a low voltage is enough to kill you, but at a really high voltage even 100mA is enough

>>57012309

stuck the tube of a dust off can into your dick, turn the can upside down, and pull the trigger.

>>57012640
Bait or just stupid? Imma go with bait.

I've taken 240V/13A/50Hz AC, 1MV/not very much at all/25KHz AC, and a fair few line-output transformer/cap shocks.

They hurt like hell, OP. Hot, painful, cramp: and with 50/60Hz your muscles jam in place so you can't move away easily.

Don't be a idiot.

>>57020103

>>57016672
Yes, usually you can tell by just the LED discharging.

>>57017294
Guess what dummy, you don't have to be touching a capacitor directly. One hand touching anywhere on the ground line and the other on the positive will get it through your heart no worries.

>>57016839

What does mains voltage have to do with the capacitor's voltage.. wait, this is a troll isn't it?

>itt: physi/g/s and ele/g/tricity

>>57015788
Spooky

buy why ?

Actual electrician here, retards saying "the amps kill you" or "the volts kill you" can fuck off. It's all about the current flowing through your body, 300mA is considered deadly. For this current to be able to move through the body, it needs the current, of course, and the "propellation" from the volts.

As to the capacitor, it is entirely possible to die from it, although jamming your hand in your fuse box with wet socks is a much more reliable course of death.

Just jump in front of a train you cocksniffing arseweasel.

There should be a bleeder resister on it to drain it over time, minutes/hours rather than years.

I accidentally shocked myself with a psu like 4 times in a row. I dont even know what the fuck it was touching that I was touching. Piece of shit was ziptied in the shell and all kinds of crazy shit. I eventually gave in and cut the zip ties.. totally worth it.
