Same artist draws about computer science too btw.

Lisanne_waifu drew TCP as an organized anime girl drinking water normally while UDP as another anime girl waterfalling it very fast at the cost or spilling a bit on her clothes.

AlfalFaFail@lemmy.ml · 56 pts · 151d (7 replies)

This is good, but it would have been nice if the symbols were more consistent. Like Volt gets a lightning bolt on her thigh... Cool. Ohm, while the sexiest in my opinion, gets an Ω on her shirt. So the under boob is great, but it's really that smile. Finally, Amp. What going on here? Those ruddy cheeks are awesome. The rope is pretty cool too even if it's not my thing. But where's her symbol? I don't particularly want to imagine a scarlet letter A.

Honestly, the inconsistency was a bit turn off.

Well... If you made it this far and think I'm missing the point, I hope you now realize I'm just taking the piss.

Electrical watersports are not safe

village604@adultswim.fan · 8 pts · 151d (2 replies)

The safety is dependent on ohms law, so the infographic is still useful

The hydraulic analogy is better (accuracy-wise)

SoleInvictus@lemmy.blahaj.zone · 8 pts · 150d (4 replies)

I absolutely love the the hydraulic analogy, and my advancing age and the 'tism compels me to share a story.

I was a science major and worked as a tutor through college. Intermediate physics was required for all science degrees, so basic electrical theory consistently came up.

What I love about the analogy is it's actually not perfectly analogous, but the differences become obvious once the initial concepts are understood, then those differences help students figure it all out. Its imperfection is actually what makes it perfect, and my nerdy side just loves that kind of stuff.

The students that argued with me the most about how it was a shit analogy were my favorite because they'd so frequently knock it out of the park come exam time. It was like the academic equivalent of hate fucking.

Crackhappy@lemmy.world · 2 pts · 149d (2 replies)

sbeak@sopuli.xyz · 19 pts · 150d

It's a reference to this image that has been shared in so many different schools around the world:

Current (measured in amperes, or amp) is the flow of charge. emf (volts) is the energy supplied to a circuit per coulomb of charge (coulombs being the unit of charge. Current is coulombs per second). Resistance (measured with ohms) restricts the flow of charge (conductors have low resistivity, insulators are high. Resistance increases with length and decreases with crosd-sectional area)

Ohm's law is V = IR (or, with current isolated, I = V / R)

Why the tire

Gormadt@lemmy.blahaj.zone · 6 pts · 149d (1 reply)

The gif is made from a Low Buck Garage video where he's working on his WW2 era 6x6 truck. The part he's staring at is the hole where the axle slots through the tire and into the differential.

This clip is taken shortly after he attempts to put the rear axle back in and he discovers that the gears in the rear most differential are no longer aligned with the hole, he shortly after this clip describes the process for what it takes to get into the rear most differential and it's an ordeal.

He does come up with a plan though.

If you're into vehicle restoration videos he's got a great channel. He's also got a great sense of humor about the stuff he works on and the processes involved.

It helps to think of it in terms of water flow. Resistance is the size of the pipe, volts is the water pressure, and amps is the flow rate.

Although resistance is an inverse relationship to pipe size (the higer the resistance, the smaller the pipe).

This image is replacing the water analogy with anime women.

WalrusDragonOnABike@reddthat.com · 29 pts · 151d (12 replies)

Volts give the push. Amps are the actual flow (charge per second). Ohms try to prevent the amps from flowing (technically restricting the charges from flowing).

DarrinBrunner@lemmy.world · 5 pts · 151d

I thought Ohm was tightening the waist, like a corset, so Amp could get through. But, maybe I was distracted.

Why is Ohms such a bitch? Let her flow.

Cause Amps can be a serious bitch when she really gets going, you've got to keep her in check.

MonkeMischief@lemmy.today · 1 pts · 150d (1 reply)

That is very educational, more than I was hoping for. Thank you!

I've heard that saying over and over throughout my life, too, (by laymen, never actual electricians lol) and I was always confused by it.

I was always trying to think "Okay is there some crazy high-voltage-low-amperage shock source you can sustain and be fine?" I guess I thought the difference was between something like, a taser vs. a home electrical socket.

Is the survivability of shocks mainly in how much resistance there is in the body? Like if the volts get backlogged enough they become amps -> generate heat -> "fry" what they're passing through?

I really need to revisit electrical education. Especially because I wanna make neat gadgets...😅

But yeah it sounds like the saying is pedantic, like "It's not the fall that kills you. It's the impact."

Something obvious to utter in a way that makes you sound deep and profound to dumb people. LOL

Arcka@midwest.social · 2 pts · 150d

Kind of, but they are misunderstanding the saying. It refers to the fact that if the available supply of current (maybe it should say power?) is sufficiently limited, it is possible for a person's body to conduct hundreds of thousands to millions of volts without pain or injury.

That said, high voltage behaves different and there are a lot of factors that make it unsafe.

speckofrust@lemmy.dbzer0.com · -8 pts · 150d (2 replies)

It’s specifically because I get out much, and am in a very long-term relationship with an actual woman that I find the idea of sexualizing cartoon images rather odd, especially when they’re very often images of children, even if not in this specific case.

I mean, there’s a discussion above of jerking off to cartoons, but I’m the one who doesn’t get out much. Keep jerkin’ it homie.

TubularTittyFrog@lemmy.world · 1 pts · 149d (1 reply)

And you don't think it's odd to judge worry about what other people's sexual fantasies are?

speckofrust@lemmy.dbzer0.com · 1 pts · 149d

Whenever it’s drawings of children, no, I don’t think it’s odd at all to worry about that. I just called it creepy, which I think it is.

No one’s getting hurt, and I’m very open to whatever people want to do to feel pleasure, but I’m also entitled to find it creepy, especially if the girls being drawn are clearly young.
