What is meant by negative half-cycle of an alternating current?
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
