• A)In recharging, the chemical reactions in both half-cells are reversed.
• B)To recharge a voltaic cell, an external voltage that is opposite to the cell potential must be applied.
• C)The negative terminal of the external power supply gets connected to the negative terminal of the voltaic cell.
• D)When a voltaic cell is recharged, the magnitude of the external voltage must be exactly the same as the cell potential.
