Correct Answer - Option 1 : Reduce the fluctuation of speed
Explanation:
Flywheel
A flywheel is a heavy rotating body which acts as a reservoir of energy. It acts as a bank of energy between the energy source and machinery. Energy stored in a flywheel is in the form of kinetic energy.
Functions of flywheel
- It is used to store energy when available and supply it when required.
- To reduces speed fluctuations.
- To reduce the power capacity of electric motor or engine.
The flywheel does not maintain a constant speed, it simply reduces the fluctuation of speed. It does not control the speed variations caused by the varying load. Governor regulates the mean speed of an engine when there are variations in the load.
