1.	In the circuit given below, `V(t)` is the sinusiodal voltage source, voltage drop `V_(AB)(t)` across the resistance `R` is A. Is half wave rectifiedB. Is full wave rectifiedC. Has the same peak value in the positive and negative half cyclesD. Has different peak values during positive and negative half cycle
Answer» Correct Answer - D In positive half cycle one diode is in forward biasing and other is in reverse biasing while in negative half cycle thier polarity reverses, and direction of current is opposite through `R` for positive and negative half cycles so output is not rectified.
