In the circuit given below, V(t) is the sinusoidal voltage source, voltage drop $V_{AB}(t)$ across the resistance R is
Answer & explanation
Correct answer: option 4
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 $R_1$ and $R_2$ are different hence the peaks during positive half and negative half of the input signal will be different.
