How does the direction of the electric current, moving across a battery powered device, differ from the direction of travel in the ac current sent to homes and businesses?

Battery = Direct Current = one directional AC = Alternating current = 2-directional So in your house, current is flowing back in forth as the voltage varies through the sine wave. In a 60Hz AC system, a complete wave occurs every 1/60th of a second.

This is from my own notes, I got the answer from here on - it helped me when I had this question last year.

Direction of electric current moving across a battery is always in one direction.

But AC current changes its direction in equal lengths of time.

This is the major difference.

Hope This Helps You!

Ibelieve the answer is b. dugout
