In half wave rectification, the output DC voltage is obtained across the load for:
Correct answer: A. The positive half cycle of input AC
- A. The positive half cycle of input AC
- B. The negative half cycle of input AC
- C. The positive and negative half cycles of input AC
- D. Either positive or negative half cycle of input AC
Explanation
In half wave rectification, the output DC voltage is obtained across the load for the positive half cycle of input AC, because during positive half cycle the circuit act as forward biased and current flows through it while during negative half cycle, it acts as reverse biased and no current flows through it.

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.
