Question

Difference between alternating and direct current.

Answer 1

ac

1. direction of current  changes with regular interval
2. it can be transmitted for long time
3. can be changed to DC

DC

1. direction of current will not change
2. cannot be transmitted for long time
3. cannot be converted to AC

Answer 2

Hey mate..

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..
