Rectifiers Quiz Question with Answer

1. In a half wave rectifier, the load current flows for what part of the cycle.

  1. 400
  2. 900
  3. 1800
  4. 3600

2. A half wave rectifier is equivalent to

  1. clamper circuit
  2. a clipper circuit
  3. a clamper circuit with negative bias
  4. a clamper circuit with positive bias

3. If the line frequency is 50 Hz, the output frequency of bridge rectifier is

  1. 25 Hz
  2. 50 Hz
  3. 100 Hz
  4. 200 Hz

4. in a full wave rectifier, if the input frequency is 50 Hz, then output frequency will be

  1. 50 Hz
  2. 75 Hz
  3. 100 Hz
  4. 200 Hz

5. In a full wave rectifier, the current in each diode flows for

  1. whole cycle of the input signal
  2. half cycle of the input signal
  3. more than half cycle of the input signal
  4. none of these

6. In a LC filter, the ripple factor

  1. Increases with the load current
  2. increases with the load resistance
  3. remains constant with the load current
  4. has the lowest value

7. In a rectifier, larger the value of shunt capacitor filter

  1. larger the peak-to-peak value of ripple voltage
  2. larger the peak current in the rectifying diode
  3. longer the time that current pulse flows through the diode
  4. smaller the dc voltage across the load

8. The basic purpose of filter is to

  1. minimize variations in ac input signal
  2. suppress harmonics in rectified output
  3. remove ripples from the rectified output
  4. stabilize dc output voltage

9. The basic reason why a full wave rectifier has a twice the efficiency of a half wave rectifier is that

  1. it makes use of transformer
  2. its ripple factor is much less
  3. it utilizes both half-cycle of the input
  4. its output frequency is double the line frequency

10. The bridge rectifier is preferred to an ordinary two diode full wave rectifier because

  1. it needs much smaller transformer for the same output
  2. no center tap required
  3. less PIV rating per diode
  4. all the above
