In a half-wave rectification, during the negative cycle of the wave, the diode is:
Correct answer: A. Reversed biased
- A. Reversed biased
- B. Forward biased
- C. Potential barrier
- D. None of these
Explanation
Option A is correct since,during the negative cycle of the wave, the diode is reverse biased and does not allow that negative half to pass.Option B is incorrect since a diode is forward biased during the positive half of the alternating cycle.Option C is incorrect since the barrier potential is very high so applied voltage cannot exceed that, this is the reason for the reverse biasing of diodes. Option D is incorrect since it states none of these, which is not the case.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
