In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth Statement I and Statement II are false
- BBoth Statement I and Statement II are true
- CStatement I is false but Statement II is true
- 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, output of the rectifier while at the same time reducing the 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 output level even higher as the capacitor acts like a storage device as shown below. Both Statement I and Statement II are true.
