Question

what is ac and dc current​

Answer 1

Explanation:

ac means alternate current

and

DC means direct current

Answer 2

Answer:

Alternating current is an electric current which periodically reverses direction, in contrast to direct current which flows only in one direction.

DC stands for Direct Current, which is electrical current that flows in one direction. In dc circuits, the current is in one direction unlike the alternating current (AC) where the current reverses direction 50 or 60 times a second depending on the frequency of the supply.
