        It’s been a decade since I studied this, but my instinct says there’s SOMETHING wrong with how amps are portrayed here.

          Amps instead current which is sorta the rate that electrons are flowing through the circuit. The picture works metaphorically but maybe your hang up is the fact that an “amp” is not the object moving through the circuit, but a bunch of little electrons.

    Okay I think I get it.

    Amps is the amount current being pushed through a circuit

    Volts is how hard the current is being pushed through the current.

    Ohms is the amount of resistance inside the current.

    More ohms or more Amps necessitates more Volts

    Bonus: watts is the rate at which the current is moving through the circuit. Volts squared divided by ohms equals watts. Amps squared times ohms equals watts. Volts times amps equals watts.

      Ohms is the amount of resistance inside the current.

      Well, it’s not inside the current, more like inside the conductor 😂, but yeah, true… more or less 😂.

      More ohms or more Amps necessitates more Volts

      You got a funny way of looking at things 😂.

      Yes, true, but I never would have thought of saying it like that 😂.

      U = I * R

      Voltage is the actual regulator of amps. Resistance is (usually) a fixed value (not fixed like Pi or e, but still, it’s considered fixed if the value doesn’t fluctuate too much). So, you need more amps? You raise the voltage. You need less amps? You drop the voltage.

      My point is, you can’t raise amps to raise voltage, doesn’t work like that.

      Bonus: watts is the rate at which the current is moving through the circuit. Volts squared divided by ohms equals watts. Amps squared times ohms equals watts. Volts times amps equals watts.

      That makes total sense, but I’ve never looked at it like that. Thanks for the POV.

        What’s funny is that I have always struggled with this subject, but for some reason this illustration made it all make sense.

          The original was with a few small people doing the same thing, this waifu version is inspired by that 😂.
