Question
What is the function of every generator?
- Changing wind energy into electrical energy
- Changing heat energy into electrical energy
- Changing mechanical energy into electrical energy
- Changing solar energy into electrical energy
Hint:
The working of all the generators is based on the Faraday's law of electromagnetic induction.
The correct answer is: Changing mechanical energy into electrical energy
The generators convert mechanical energy into electrical energy.
- The generators use magnets to generate electrical energy.
- The current generated is an alternating current.
- They convert the mechanical energy provided from an external source, to electrical energy to provide enough energy for other appliances.
- Its working is based on the Faraday law of electromagnetic induction.
