Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
