Semiconducting Devices Question 44
Question: In the circuit given below, V(t) is the sinusoidal voltage source, voltage drop VAB(t) across the resistance R is
[IIT 1993]
Options:
A) Is half wave rectified
B) Is full wave rectified
C) Has the same peak value in the positive and negative half cycles
D) Has different peak values during positive and negative half cycle
Show Answer
Answer:
Correct Answer: D
Solution:
In positive half cycle one diode is in forward biasing and other is in reverse biasing while in negative half cycle their polarity reverses, and direction of current is opposite through R for positive and negative half cycles so out put is not rectified.
Since R1 and R2 are different hence the peaks during positive half and negative half of the input signal will be different.
