In the circuit given below, v(t) is the sinusoidal voltage source, the voltage drop VAB(t) across the resistance R is, and diodes D1 and D2 are identical:
Correct answer: B. No rectification and has the same peak value in the positive and negative half cycles
- A. Full wave rectified
- B. No rectification and has the same peak value in the positive and negative half cycles
- C. No rectification and has different peak values during positive and negative half cycles
- D. Half wave rectified
Explanation
The direction of current is opposite through R for positive and negative half cycles, so the output is not rectified. Since R1 and R2 are the same. Hence, the peaks during the positive half and the negative half of the input signal will be the same.

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.
