Question

define dc and ac current

Answer 1

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

Heya...

Answer __________

Direct current :-

√ It is the flow of electric current in the one direction only or it is unidirectional flow of electricity...

Alternating current :-

√ It is the flow of charge that changes the direction periodically...
It can be travel in zigzag circuit..
