In the circuit given below, `V(t)` is the sinusoidal voltage source, voltage drop `V_(AB)(t)` across the resistance `R` is

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

Text Solution

Verified by Experts

The correct Answer is:
D
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 output is not rectified.
