In a full wave rectifier, the output voltage obtained is in the shape of pulsating half sinusoids which are unidirectional but not steady. To get a steady d.c. output
(A) An inductor can be use in series with the load resistor
(B) A capacitor of high value of capacitance can be used in parallel with the load resistor
(C) A capacitor of low capacitance can be used in series with the load resistor(D) Only load resistor is enough to filter out the pulses and convert them to d.c.
Choose the correct answer from the options given below:

  1. A (C) and (D) only
  2. B (A) and (B) only
  3. C (A), (B) and (D) only
  4. D (D) only

Answer & Solution

Correct Answer

(B) (A) and (B) only

Step-by-step Solution

Detailed explanation

(A) and (B) only (A) An inductor can be used in series with the load resistor: An inductor opposes changes in current. When placed in series, it smooths out current variations, acting as a choke filter. This helps in getting a steadier d.c. output. (B) A capacitor of high value…
