Question

Explain electromotive force and internal resistance of a cell

Answer 1

ELECTROMOTIVE FORCE


a difference in potential that tends to give rise to an electric current
Electromotive Force and Internal Resistance. The electromotive force (e) or e.m.f. is the energy provided by acell or battery per coulomb of charge passing through it, it is measured in volts (V). It is equal to the potential difference across the terminals of thecell when no current is flowing.
