My understanding is power is expended when current flows through a metal with resistance, and that loss is in the form of heat. The lower the resistance, the lower the loss and therefore lower the heat
- TekMol 3y agoBut you do lose energy as current flows. When you start with 10 elecrons on the left of the wire and none on the right and end up with 5 on both sides, you lost all energy that was stored in the system.
- desmond1303 3y agoThe mind-blowing thing is that electrons, as far as I understand it, don't actually flow through wires at all. If they did AC power would be pointless
- actionfromafar 3y agoWell they do but very slowly. With AC they just wiggle left and right.
- htfu 3y agoThis is some kind of a simplified view of how a battery works. It is not how an electric field functions.
