Question

a cell is connected across a resistance of 50 ohm which provide a current of 2 ampere find the potential difference provided by cell and find the amount of charge following through a circuit in 1 minute also find the amount of energy consumed from the cell in 1 minute​

Answer 1

Electromotive Force and Internal Resistance. The electromotive force (e) or e.m.f. is the energy provided by a cell 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 the cell when no current is flowing.
