Question

Find an expression for internal resistance of a cell

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.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

Internal resistance of a cell is defined as the resistance offered by the electrolyte to the flow of current through the cell.internal resistance of a cell (r) depends upon the nature of electrolyte and electrodes...
