During negative half cycle of AC, PN junction offers?
During negative half cycle of AC, PN junction offers?
Explanation
A PN junction diode allows current to flow only in one direction — from P to N (forward bias).
During the positive half cycle of AC, the diode is forward-biased (low resistance), so current flows.
During the negative half cycle, the diode is reverse biased, so it blocks current and offers high resistance.
