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 load R L . 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 with R L . In the light of the above statements, choose the most appropriate answer from the options giv

Options

  1. ABoth Statement I and Statement II are false
  2. BBoth Statement I and Statement II are true
  3. CStatement I is false but Statement II is true
  4. DStatement I is true but Statement II is false

Correct answer

B. Both Statement I and Statement II are true

Step-by-step solution

We can improve the average, D C output of the rectifier while at the same time reducing the A . 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 average D C output level even higher as the capacitor acts like a storage device as shown below. Both Statement I and Statement II are true.
