Question

In the circuit given below,V(f)is the sinusoidal voltage source, voltage drop $V_{AB}\left(t\right)$ across the resistance R is

• A. Has different peak values during positive and negative half cycle
• B. Is full wave rectified
• C. Is half wave rectified
• D. Has the same peak value in the positive and negative half cycle

Answer 1

Answer: (A)

Has different peak values during positive and negative half cycle

In positive half cycle one diode is in forward biasing and other is in reverse biasing while in negative half cycle their polarity reverse, and direction of current is opposite through $R$ for positive and negative half cycles so cut put is not rectified.

Since $R_1$ and $R_2$ are different hence the peak during positive half and negative half of the input signal will be different.
