Hi, I'm just starting to study circuits, and there's a thing I don't understand about electric potential. I was under the impression that as a charge moves through the circuit from the high potential end of the battery to the low potential end, it lost electric potential energy which became kinetic energy. However, I found this graph: In circuit B, the diagram states that from A to B the electric potential stays at 6V. Surely the charge would lose some electric potential and gain some kinetic energy? Can anyone explain this? Thanks!
