Fossil fuels, such as coal, natural gas, and oil, are burned in power plants to produce electricity. The combustion of these fuels generates heat, which is used to convert water into steam. This steam then drives a turbine connected to a generator.
**How an Electric Generator Works:**
1. **Mechanical Energy**: The turbine, rotated by steam or combustion gases, converts thermal energy into mechanical energy.
2. **Rotation of the Rotor**: The rotating turbine drives a rotor inside a generator. The rotor is composed of magnets or coils of wire.
3. **Electromagnetic Induction**: As the rotor turns, it moves past stationary coils of wire (the stator). This movement creates a change in magnetic field, inducing an electric current in the coils according to Faraday's law of electromagnetic induction.
4. **Electricity Generation**: The induced current is then collected, transformed, and sent to the power grid for distribution to homes and businesses.
This process efficiently converts the chemical energy stored in fossil fuels into electrical energy used for various applications.
