The output frequency of a (i) half-wave rectifier and (ii) full-wave rectifier, if the input frequency is 50 Hz are, respectively
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (i) 50 Hz; (ii) 100 Hz
The output frequency of a rectifier is the number of output pulses per second.
A half-wave rectifier passes only one half of each input cycle, so it gives one pulse per cycle: output frequency = input frequency = 50 Hz.
A full-wave rectifier uses both halves of each cycle, giving two pulses per cycle: output frequency = \( 2 \times 50 = 100\,\mathrm{Hz} \).
