Question

Why is the use of A.C. voltage preferred over D.C. voltage ? Give two reasons.

Answer 1

The use of A.C. voltage is preferred over the use of D.C. voltage because of the following reasons:

(i) The loss energy in transmitting the A.C. voltage over long distances with the help of step up transformers is negligible as compared to D.C. voltage.

(ii) A.C. voltage can be stepped up and stepped down as per the requirement using a transformer.
