Asked by  | 15th Feb, 2009, 12:28: PM

Expert Answer:

1. The amplitude of AC current varies with time  whereas the current in DC is constant.

2. The direction of an AC current  reverses periodically  but the DC current flows in a single direction.

3. A mutual induction can occur in AC current which is not posible in DC current.
