Answer 2

Hello Friend !!!

Alternating current (AC) is a type of electric current that periodically reverses direction, in contrast to direct current which flows only in one direction. It is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight.
