Question

Advantages of A.C. over D.C.

Answer 1

1.The ac is easy to generate than dc.
2.It is cheaper to generate ac than dc.
3.The ac generators have higher efficiency than dc.
4.The loss of energy during transmission is negligible for ac.
5.The ac can be easily converted into dc.
6.The variation of ac can easily be done using transformers either step up or step down.

Hope it helps....

Answer 2

Advantage and disadvantage of AC over dc

ADVANTAGES

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 energyA.C. can easily be converted into D.C. with the help of rectifiers.When A.C. is supplied at higher voltages in long distance transmission , the line losses are small compared to a D.C. transmission
