The circuit shows in Fig .shows the use of potentiometer to measure the internal resistance of a cell. (a) When the key is open, how does the balance point change, if the driver cell decreases ? (b) When the key is closed, how does the balance point change, if R is increased, keeping the current from the driver cell constant ?
