4.7: Electromotive Force and Internal Resistance
The internal resistance of a lead-acid cell is typically quite small, but most dry cells have an appreciable internal resistance. If the external resistance is (R) and the internal resistance is (r), the total resistance of the circuit is (R + r), so that the current that flows is E(/(R + r)). Whenever a current is taken from a cell (or ...
