Use of a.c. voltage is preferred over d.c. voltage on account of the following reasons:
(i) An a.c generator is easy to operate and maintain. So we prefer to use a.c. voltage.
(ii) Using a Transformer voltage of a.c supply may be suitably increased or decreased.
(iii) a.c. power may be transmitted over long distances without much loss of energy.

The use of alternating current (A.C.) voltage is preferred over direct current (D.C.) voltage for two main reasons:
Easy Voltage Transformation: A.C. voltage can easily be stepped up or stepped down using transformers, making it efficient for long-distance transmission.
Simpler Generation and Distribution: A.C. generators are simpler and cheaper to design and maintain compared to D.C. generators, and A.C. can be easily converted to various forms of energy for different applications.
