| Sources of Electricity |
|
| Batteries |
| |
 |
| |
| Batteries produce electricity by converting chemical energy into electrical energy. Batteries provide electricity to torches, transistors, toys, clocks and watches. |
| |
| Generators |
| |
 |
| |
| Generators are devices that produce
electricity by converting mechanical energy into electrical energy. It works
on the principle of 'electromagnetic induction' [Electromagnetic Induction
is the creation of a voltage or current due to change in magnetic field].
Most of the electricity supply for industries and towns come from
generators. |
| |
| Solar Cells |
| |
 |
| |
| Solar cells convert light energy of the sun into electrical energy. They provide almost the complete power for required space crafts and artificial satellites. |
| |
| Nuclear Reactors |
| |
 |
| |
| The nucleus of an atom possesses high amount of energy which can be used for the electric power generation in nuclear reactors. Here nuclear energy gets converted into electrical energy. |
