MCQ
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
  • Has different peak values during positive and negative half cycle

Answer

Correct option: D.
Has different peak values during positive and negative half cycle
d
(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 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.
