Following are the sources of electricity:

01. Dry cell - It is a device that can convert chemical energy into electrical energy. It can be further divided into the following catagory:
a) Primary cell
b) Secondary cell

02. Electric generator:

Electric generator is a device that generates electricity. A british Scientist, Michael Faraday, prooved that if a copper coil is quickly rotated in strong magnetic field, electricity is generated in the copper coil. In this process, mechanical energy is converted into electrical energy.

03. Solar cell:
A solar cell is a device that converts solar energy into electrical energy. This electrical energy thus generated is stored in storage cells or accumulators. Solar cells are used in wrist watches and calculators.
