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
Explanation
The correct answer is "a) The positive half cycle of input AC." Half-wave rectification produces an output DC voltage only during the positive half cycle of the input AC voltage. The negative half cycle does not contribute to the output voltage. The other options (b, c, and d) do not represent the correct behavior of half-wave rectification.

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.
