Detailed Solution

The above statement is true.
Transformers can change the voltage of AC. The magnitude of AC can be reduced using a choke coil without involving loss of energy.
Alternating current: The electric current which reverses its direction after a certain fixed interval of time is called alternating current. Thus, in AC, the positive and negative polarities are not fixed.
The electricity supplied to our homes and industry is AC.
It can be transmitted over long distances with negligible loss of energy.
Since power wastage in AC transmission is almost negligible, the cost of AC transmission is low. When required, AC can be changed into DC.
