Correct answer: C. B, D
- A. C
- B. A
- C. B, D
- D. A, B, C, D
Explanation
Considering the typical behaviour of a full-wave rectifier, option 3 (BD) is the most likely correct answer. In a full-wave rectifier circuit, each diode conducts during a half-cycle of the input waveform, resulting in rectification. However, due to the presence of ripple, the output will have fluctuations.Option 1 (C) is unlikely since a constant DC component without any ripple is not a characteristic of a full-wave rectifier.Option 2 (A) assumes that diode 1 does not play a role in the rectification process, which contradicts the purpose of a full-wave rectifier.Option 4 (ABCD) suggests a smooth DC output without any ripple, which is not typically achieved in a full-wave rectifier unless additional filtering components, such as capacitors, are added to the circuit.

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.
