4.

A single-phase half-wave type diode rectifier requires __________ number of diode(s) whereas full wave type requires _________ number of diode(s)

• 4, 1

• 1, 4

• 1, 3

• 3, 4

If the peak value of a sinewave is 120 V, when it is rectified by a bridge rectifier the average value is:

• 76.39 V

• 0.6366 V

• 84.85 V

• 38.2 V

If the peak-to-peak value of a sinewave is 12 V, when it is rectified by a halfwave rectifier the average value is:

• 3.82 V

• 4.243 V

• 8.485 V

• 1.91 V
