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:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (C) and (D) only
(A) Correct — In full-wave rectifier, both diodes conduct alternately, not simultaneously one forward and one reverse.
(B) Correct — Output frequency = 2 × input frequency.
(C) Incorrect — In full-wave rectifier, current through load always flows in the same direction (unidirectional).
(D) Incorrect — Output voltage is pulsating, not uniform; filtering is required to make it uniform.
Incorrect statements: (C), (D)
