Question

What is the difference between direct current DC and alternating current AC ?

Answer 1

Answer:

Direct current (DC) is the flow of electric charge in only one direction. ... Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidally, the circuit is known as an alternating current circuit.

Answer 2

Answer:

ac current change its direction during flow while DC current does not change its direction during flow and remains constant.
