Statement I : To get a steady DC output from the pulsating voltage received from a full wave rectifier we can connect a capacitor across the output parallel to the loadRL.
Statement II : To get a steady DC output from the pulsating voltage received from a full wave rectifier we can connect an inductor in series withRL.
In the light of the above statements, choose the most appropriate answer from the options given below :

Options:

Answer:
B
Solution:

We can improve the average,DCoutput of the rectifier while at the same time reducing theA.C.variation of the rectified output by using smoothing capacitors to filter the output waveform. Smoothing or reservoir capacitors connected in parallel with the load across the output of the full-wave bridge rectifier circuit increase the averageDCoutput level even higher as the capacitor acts like a storage device as shown below. Both Statement I and Statement II are true.
