Confusion between positive and negative terminals of a battery
Outside a battery, current flows from its positive terminal to its negative terminal. Inside the battery, to stop charge building up, the current must flow the rest of the way round, from the negative terminal to the positive terminal. This flow is driven by the chemical reactions in the battery. In an electrolysis cell the current flows ...
