Assertion:- To cells of unequal emf E_(1) and E_(2) having internal resistances r_(1) and r_(3) are connected as shown in figure. Then the potential difference across any cell cannot be zero. Reason:- If two cells having nonzero internal resistance and unequal emf are connected across each other as shown, then the current in the circuit cannot be zero.
