Detailed explanation-1: -Alternating Current Explained Every so often, the electrons change direction. In alternating current, the electrons don’t move steadily forward. Instead, they just move back and forth.

Detailed explanation-2: -When electric charge flows in one direction it’s called direct current and when the electric charge wiggles back and forth, alternating directions, it’s called alternating current.

Detailed explanation-3: -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.
