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:

(A) and (B) only

The correct answer is Option (2) → (A) and (B) only

In a full wave rectifier, the output voltage is a pulsating DC (unidirectional but varying).

To obtain steady DC, a filter is used:

(A) An inductor in series with the load resistor smooths the current → reduces ripple → improves DC output.

(B) A capacitor of high capacitance in parallel with the load charges during peaks and discharges during valleys → smooths voltage → steady DC.

(C) A capacitor in series is not effective for filtering → does not produce steady DC.

(D) Only load resistor is not sufficient → ripple remains.
