alleryIn alternating current, what happens to the movement of charge?
AIt stops each second
BIt flows one way only
CIt keeps reversing
DIt moves only in vacuum
Answer & Solution
Correct answer: C. It keeps reversing
1. In AC the movement of electric charge periodically reverses direction.
2. Flow in one way only describes DC.
3. So periodic reversal is correct.
