Question

Which of the following devices converts chemical energy into electrical energy ?
1. Generator
2. Battery
3. Dynamo
4. Invertor

Answer 1

Correct Answer - Option 2 : Battery

The correct answer is Battery.

• A battery is a device that stores chemical energy and converts it to electrical energy.
• The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
• The flow of electrons provides an electric current that can be used to do work. 

• A generator converts the mechanical (kinetic) energy of the rotor to electrical energy.
• A dynamo also called an electric generator, is simply a machine that converts mechanical energy into electricity. Dynamos are most often found inside power plants.
