Fig. shows three circuits used to rectify an alternating current. A cathode ray oscilloscope (CRO) with fixed settings of time base and Y gain is connected in turn as shown and produces a different trace in each case. Which of set of diagrams shows these traces most accurately?
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
1st circuit represents half-wave rectification and 2nd circuit represents filtered output with the help of capacitor and 3rd circuit represents output of full wave rectification.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
