Mention two advantages of А.С. over DC. ?

Answer»

The generation of A.C. is cheaper than that of D.C.

A.C. machines are simple , robust and do mot require much attention for their repairs and maintainance during their use.

Wide range of voltages are obtained by the use of transformer.

The magnitude of current can be reduced by using an inductance or a conductor without any appreciable loss of energy

A.C. can easily be converted into D.C. with the help of rectifiers.
