I don’t get this, cause I’m stupid, but maybe someone will find this funny.

That is pretty good. Current is roughly the flow rate of electricity through a material and is measured in Amperes. Resistance measured in Ohms is what restricts current from passing through a material. Voltage is the measure of the “pressure” that pushes the electricity through a material.
I still prefer the water metaphor. I don’t want to imagine a hot girl dancing around my circuit undergoing various levels of BDSM-level bondage, whilst being bullied by the spiciest girl on the board
Almost all electric heaters work by having enough ohms in their coils to turn the standard american 120 v,15amp circuit 100% into heat.
By the above analogy, electric heaters are basically perfectly efficent bondage dungeons staffed by endless Ohm baddies.
Why not?
Because I don’t like to be erect when handling a hot soldering iron
How else are you going to take sounding to the next level?
Must be his first time
I remember hearing the water analogy is technically incorrect in a way that ultimately makes it bad to use for intuition but can’t remember why.
This seems to demonstrate the same idea so now I wonder if I’m thinking of something else 🤔
Edit: actually it might have had something to do with protons and physics nerds
I had the water thing explained to me so many times and I could never get it intuitively. I’m not sure why. These ladies are just the water analogy again.
What finally worked for me was someone describing it to me like a bike chain of electrons. Maybe because I’m too dense to conceptualize a really tiny liquid inside a solid. But once it was described like amps are how many links go by, ohms makes it harder to move, and volts push the chain and it’s a CIRCLE, and they are always touching each other. I was set.
Maybe that’s what you remember, water doesn’t intuitively link to the concept of a circuit or the chain of electrons.
There’s still the possibility I didn’t understand this analogy either, but at least I feel more confident.

Charge: Unlike water, movable charge carriers can be positive or negative, and conductors can exhibit an overall positive or negative net charge. The mobile carriers in electric currents are usually electrons, but sometimes they are charged positively, such as the positive ions in an electrolyte, the H+ ions in proton conductors or holes in p-type semiconductors and some (very rare) conductors.
I think this is the main one where it breaks down for me
It’s a reasonably ok metaphor for talking about power transfer but not information transfer. Analytical solutions for charge and fluid flow reduce to very similar differential equations. However for information flow, the models don’t actually require charge to be exchanged, only that we can measure the fields which result from moving charge around. This means the boundary conditions for information transfer are established by quantum effects in the receiver. Literally the Brownian motion of doped semiconductor material expressed in terms of thermal entropy. That establishes the floor for how many individual atoms must do something coherently for it to be statistically separable from what atoms do without an information stimulus.
And superconductors give us current with 0 resistance!
Fuck: Volt Marry: Ohm Kill: Amp
Fuck = Marry x Kill
Jesse, wtf are you talking about? 😭
Lol, iykyk
Anyone got Ohm’s phone number?
This is probably genuinely a better explanation than I got through my entire undergrad.
Same for me, however I must state that the quote “everyday stray further away from god”, in it’s essence should still be considered in modern society. Is there a non-religious way to say “y’all need Jesus”?
Usually it is
It works so well describing different scenarios. If there are hundreds of Amps, they all get hot and sweaty trying to fit through the gap. You can reduce the temperature by either getting Ohm to loosen up on the rope or you can increase the volts to push her through faster.
Half right. Reducing ohms does reduce heat, but if you increase volts only on the input the power dissipation goes up by the square of voltage.
When you raise the voltage on both input and output (like high tension power lines) only the difference stays the same. In that case the heat stays the same but the amount of useful power getting through the resistance is higher so the heat is a smaller fraction of the total power getting through.
Maybe my imagination is too limited, but I am not sure whether this cute illustration helps explain any of that. Maybe we should spend less time pushing analogies through tight spots and relax.
also the hotter is it te harder is ohm pulling the rope
Best version of this explanation
Someone more knownedgeable than me will follow shortly but that’s a cheeky way to ilustrate Ohm’s Law.
Now explain skin effect.
Eeeeeeeh…
Okay, bear with me here…
Testosterone. Skin thicc. Skin rough. Also hairy. Not smooth! But durable. Also oily.
Estrogen…skin thin. But that mean smooth! Very smooth. Less hairy, more smooth! Less durable, many cut and bruise. Also dry, omfg dry. But…worthHormone effect skin. Explained 👍
Skin effect with current is when the majority of the actual electron flow is on the surface of the conductor.
To tie your point into the explaination, it’s like when you have a finger traced over some soft, smooth skin, and you feel that tingle. I guess? I don’t think I’m doing it justice with words, I may just have to show you.
I actually know what skin effect is, I was just being silly 😆
Thanks for trying to explain it anyway! <3
