The input a.c. voltage of frequency \(60 \mathrm{~Hz}\) is applied to half-wave rectifier and also to full-wave rectifier. The output frequency in case of half-wave rectifier and that in case of full wave rectifier is respectively.
- A \(120 \mathrm{~Hz}, 60 \mathrm{~Hz}\)
- B \(60 \mathrm{~Hz}, 120 \mathrm{~Hz}\)
- C \(60 \mathrm{~Hz}, 60 \mathrm{~Hz}\)
- D \(120 \mathrm{~Hz}, 120 \mathrm{~Hz}\)
Answer & Solution
Correct Answer
(B) \(60 \mathrm{~Hz}, 120 \mathrm{~Hz}\)
Step-by-step Solution
Detailed explanation
In a half-wave rectifier, one pulse is obtained for each wave and hence 60 pulses will be obtained per second. In a full wave rectifier, two pulses are obtained for each wave and 120 pulses are obtained per second.
