Key Topics to Revise
1
1. Electromagnetic induction and the generator
- Most electric power plants work on electromagnetic induction.
- When the magnetic field around a conductor changes, a potential difference is generated across the conductor.
- The field around a conductor can be changed by rotating a magnet near a stationary conductor or by moving the conductor near a stationary magnet.

2. Thermal power plant
- Coal is used as the fuel in a thermal power plant.
- Coal burns in a boiler and releases thermal energy.
- Water in the boiler is heated to produce steam of very high temperature and high pressure.

3. Nuclear power plant
- A nuclear power plant also uses a turbine and a generator.
- Uranium-235 is bombarded with a neutron.
- Uranium-235 absorbs the neutron and becomes Uranium-236.

4. Natural gas power plant
- Natural gas power plants use a compressor, a combustion chamber, a turbine, and a generator.
- Pressurised air is introduced into the combustion chamber by a compressor.
- Natural gas burns in the combustion chamber in the presence of air.
