Question

Distinguish between a.c and d.c source. (at least 3 points each)

Answer 1

$\Huge{\bold{\mathrm{\underline{\red{ANSWER}}}}}$

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

Answer 2

Answer:

DC has no frequency of zero frequency. In AC the flow of current changes its direction backwards periodically. It flows in a single direction steadily. Electrons only move in one direction – that is forward.
