A Wien-bridge oscillator is basically a _____.
Answers: • sine-wave generator
A voltage V=300cos100t is applied to a half wave rectifier with RL =5KΩ. The
rectifier may be represented by an ideal diode in series with a resistance of
1KΩ. What would be the ripple factor in this case?
Answers: • 100%
A bridge rectifier circuit has secondary voltage of 12Vr.m.s. Assume secondary
resistance and diode forward resistance to be negligible. The load resistance is
100Ω. What would be the peak load current?
Answers: • 0.169 Amp
A half wave rectifier supplies power to 1000Ω load from a 110V (r.m.s) source of
supply. If the forward resistance of the diode is 20Ω. What would be the
efficiency of the rectifier?
Answers: • 39.73%
