What is difference between AC and DC current

1.	What is difference between AC and DC current
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. This is full form give meaning In ac electricity consumption is less as compared to dc Ac is alternating current whreas dc is direct current.
