Answer:
The emf of the cell is E and internal resistance is r which draws a current I. Terminal voltage is the output voltage of a device which is measured across its terminals. = voltage output of a device. The emf of a cell is always greater than its terminal voltage.

Explanation:
The internal resistance r of a voltage source affects the output voltage when a current flows. The voltage output of a device is called its terminal voltage V and is given by V = emf − Ir, where I is the electric current and is positive when flowing away from the positive terminal of the voltage source.
