Question

Quizplus · Accepted Answer

Batteries work by chemical reactions that create a flow of electrons from one terminal to another. This flow of electrons, or current, goes from the negative terminal to the positive terminal, effectively "pumping" positive charge in the opposite direction, from the positive terminal to the negative terminal, due to the nature of electric current and charge flow.
