Question

Name two sources of electricity.

Answer 1

Explanation:

1. Electricity is defined as the rate of flow of charges in a conductor.
2. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy.
3. There are different ways to produce electricity using different sources like coal Electric generators and Solar cells.

Electric generator:

An electric generator is a device which converts mechanical energy into electrical energy. which works on the principle of electromagnetic induction.

1. Thermal power plant:

1. In a thermal power plant thermal energy is converted into mechanical energy and mechanical energy into electrical energy.
2. The source of thermal energy is coal, fossil fuels, nuclear, biomass, and geothermal.

2. Hydraulic power plant:

1. In a hydraulic power plant hydraulic energy is converted into mechanical energy and mechanical energy is converted into electrical energy. which works on the principle of electromagnetic induction.
2. The source of hydraulic energy is water stored in a dam.

Solar Cell:

1. A solar cell converts solar energy into electrical energy by the photovoltaic cell
