Why is terminal voltage of a cell less than its emf?

Asked by aishwarya S 27th September 2013, 2:26 PM
Answered by Expert
EMF of a cell is the voltage measured between the terminals of a cell when it is not connected to external circuit, that is, when it is not delivering any current.
When the cell delivers a current, part of the current is utilised by the internal resistance of the cell and the remaining goes in the circuit, which is known as the terminal voltage.
Thus, terminal voltage is less than the emf of the cell.
