Question

A galvanic cell or voltaic cell converts:

• A. Chemical energy into electrical energy
• B. Mechanical energy into electrical energy
• C. Light energy into electrical energy
• D. Electrical energy into chemical energy

Answer 1

The correct option is A Chemical energy into electrical energy

The devices which convert electrical energy into chemical energy or vice versa is called Electrochemical cell.
There are two types of electrochemical cell,
1. Galvanic Cell
2. Electrolytic Cell

Galvanic cell is also known as Voltaic cell. It converts the chemical energy liberated during the reaction to electrical energy. The chemical reaction will be a spontaneous reaction.

In Electrolytic cell, electrical energy is being used to carry out chemical reactions (chemical energy). Here, the electric current drives a non-spontaneous reaction.
