A full-wave rectifier is used to convert ‘\(n\)’ \(Hz\) \(a\).\(c\) into \(d\).\(c\), then the number of pulses per second present in the rectified voltage is
1 \(n\)
2 \(n/2\)
3 \(2n\)
4 \(4n\)
Explanation:
For a full wave or bridge rectifier the frequency of the output wave form is twice the mains frequency.

Constant \(DC\) voltage is required from a variable \(AC\) voltage. Which of the following is correct order of operation?
1 Regulator, filter, rectifier
2 Rectifier, regulator, filter
3 Rectifier, filter , regulator
4 Filter, regulator, rectifier
Explanation:
A rectifier converts \(AC\) into pulsating \(DC\). A filter then removes the pulsations and a regulator finally produces the required constant output voltage.

A full-wave rectifier with diodes \(D_{1}\) and \(D_{2}\) is used to rectify \(50\;Hz\) alternating voltage. The diode \(D_{1}\) conducts____ times in one second.
1 75
2 50
3 100
4 25
Explanation:
A Full wave rectifier shows output for both the half cycles of \(A C\) input. The output frequency of waveform across \(D_{1}\) diode is \(50\;Hz\) and \(D_{2}\) diode is \(50\;Hz\) and so for total output it is \(100\;Hz\). Correct option is (2).
