CONCEPT:

Galvanic Cell

• A galvanic cell, also known as a voltaic cell, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.
• In a galvanic cell, chemical energy is converted into electrical energy.

EXPLANATION:​

• The correct name for a galvanic cell is a voltaic cell.
• Mercury cell is a type of primary cell that uses mercury oxide as the cathode.
• Leclanche cell is a type of primary cell commonly used in batteries.
• Secondary cell refers to rechargeable batteries.
