Choose the incorrect statements from the options given below:
(A) In making a full wave rectifier, the two diodes are connected, with one in forward bias and the second in reverse bias.
(B) In a full wave rectifier, the output frequency is twice the input frequency.
(C) In a full wave rectifier, the current through the load resistance flows in one direction for half cycle and in the reverse direction for the other half cycle.
(D) In a full wave rectifier having two diodes and a resistance, the output voltage is uniform
Choose the correct answer from the options given below:
- A (A) and (B) only
- B (A) and (C) only
- C (A) and (D) only
- D (C) and (D) only
Answer & Solution
Correct Answer
(D) (C) and (D) only
Step-by-step Solution
Detailed explanation
(B) is correct. (C) is incorrect. Current through the load flows in one direction only. (D) is incorrect. Output voltage is pulsating, not uniform, without a filter. The phrasing of (A) is ambiguous, but its core idea of alternating diode conduction is fundamental to full-wave…
