The ripple factor of a full-wave rectifier circuit compared to that of a half wave rectifier circuit without filter is
- A. half of that for a half wave rectifier
- B. less than half that for a half-wave rectifier circuit
- C. equal to that of a half wave rectifier
- D. more than half that for a half-wave rectifier circuit
Answer: B. less than half that for a half-wave rectifier circuit
Explanation: The ripple factor of an unfiltered half-wave rectifier is 1.21, whereas for a full-wave rectifier it is 0.482. Since 0.482 < (1.21/2 = 0.605), it is less than half that of a half-wave rectifier.
