Because the result isn't even close to DC.

>>60674621
This. Every engineer besides civil can verify.

>>60674653
Don't forget about Product """engineers""", QA """engineers""", marketing """engineers", etc.

>>60674578
other than lack of full bridge rectifying, like many pouted out.

It's not very safe, one surge could destroy the single diode and AC would rush the other end.

I got all except the first one. It's obviously better (a quick google of SL2831 gives that straight away), but I'm not sure what current-mode control is all about.

>>60674653
As a civil engineer even I can verify.
We do have physics, and electronic measurements courses required.
(just so we can use tensometers)

Also there's no smoothing capacitor, so the DC output would be noisy depending on the noise in the AC line.

>>60674578
EE here, quality meme thanks for the kek.

What do the others look like?

and Software """""""engineers""""""""

>>60675520
That's the raw rectifier output. The middle two circuits have smoothing capacitors to make that closer to DC

>>60675520
the third one will be relatively more smooth, and the second one will be pretty much smooth to the limits of the linear regulator

>>60675452
in the second one the linear regulator will smooth it to 5V DC

in the third one the cap will smooth it to 9V DC with no load, getting less smooth the more load you connect

Here is a look at what the capacitors do in 2 and 3

>>60674578
Because you only get DC on the top wire

>>60674599
You wont tho

>>60674578
If one of our engineers/workers ever made something like the bottom one as a DC source, we'd sack him immediately.

>>60675714
But he is saving the company millions in parts

>>60675714
What if a woman or nigger engineer made it?

>>60675772
It'd cost more a lot more in the aftermath.

>>60675801
Sacked. It doesn't matter here in Germany what your label is. If you're not suited for the job, you're either out or doing something else. That one would be a giant fuckup, violating rules, common sense and probably damaging the company. They can feel free to sue us, though. But they shouldn't get their hopes too high, they might even lose more than they gambled for.

Shouldn't this meme have its contents ordered from worst to best in accordance to the brain scans, not best to worst?

>>60676509
it's a meme you dip

>>60676546
Who cares if its a meme? What is its internal logic? How does one replicate this meme?

>>60676509
That's the joke.

>>60676736
Fuck you firefox, stop putting that name i used once back in the name field. wtf.

>>60676750
most likely that's 4chanX or some other plugin

>>60676707

The meme does have the "internal logic" that the worst result is at the bottom.

It's called irony..

>>60676265
Can we please stop pretending using an IC regulator isn't the best idea, k thanks.

>>60676265
So the last one is bad because, while technically working, most of the energy will be wasted on heating R1?
No bully pls, it's been a long time since my EE classes.

>>60675551
I'm a certified software engineer, in my country we have software engineering degree and yes we do physics, electronics and tons of math.

>>60675560
The second one is actually rectified, so it is perfect dc

I'm a """software engineer""". Not by name I only call myself "programmer" and thats ok but I have a BSCS but no idea of electronics.

How much time would one need to invest to understand diagrams like this and how would one start? Not trying to become an EE but maybe get some basic ideo of the machines I'm using.

Perhaps take electrical engineering 101 at a local uni?

>>60677321
If it's anything like my CS 101 then it'll be absolutely useless for any kind of practical work. But granted half of my degree was a big meme anyway. Maybe I'll check it out.
Any books or something tho?

>>60677194
Start by studying pure mathematics for 8 years.

Last pic's output is the second/third graph in pic related.

>First pic - Don't want to actually look at it, but essentially looks like a 120V AC to USB output.
>Second pic - Should have a near-baby-smooth +5V output due to use of caps and the voltage regulator.
>Third pic - Should have a relatively smooth +5V output since it's the second pic minus the voltage regulator. It'd look like the fourth graph in pic related but with the zero closer to +5V.

This is also ignoring the fact that the first pic is the only one with anything protecting the system. The next three pics look like they'd be used for just simulation or demo purposes.

It's DC though.

>tfw I have no idea and I graduated with a EE and CE degree
At least all I do now is program, I didn't realize I fucking hated doing analog circuits until I was almost done with my degree.

>>60677840
Hey man I know nothing about electronics and have been considering going back to university to study it, maybe in the form of EE. Do you think it's worth it or I should self teach?

>>60677884
It depends on what you want to do. If you want to be an engineer and get an engineers salary you'll have to go to school. Sometimes you can get by with experience alone but you'll need like 10+ years in the field and you won't get paid as much, even if you're smarter and do better work than others.

>>60675663
That diode prevents the flow of current in the opposite direction. So it would block half the power.

>>60675551
Studying for Engineer in computer science here
Had to take physics/calculus class like people on electric and have to take a class on electronics

>tfw got d+ in electronics II
As CE can confirm, should've just taken CS.

>>60677963
Sometimes I wonder if it would have been better if I just switched to CS right away. I like programming for hardware though and most CS people don't do that.

The real twist is that the light coming from the brains is actually sparks as the person is getting electrocuted by the circuits

>>60677963
Multi-stage and amplifiers, oscillators, and differential amplifiers/circuits?

>>60677998
yeah, I feel as though I'd have been destined for embedded either way.

Less than a day for all of them except the first

I basically stopped going half way through the course, but yeah. depression, yo

>>60678045
Oscillators are cancer in general desu. At least it's not RF circuits.

>>60677194
The bottom few aren't too hard to understand, really. First, look up some basic stuff about current, voltage, power, and the like, then try to find what the symbols on the drawing mean and look that up. Hour tops with Wikipedia to understand what's going on a basic level.
