MCQ
In the circuit given below, $V ( t )$ is the sinusoidal voltage source, voltage drop $V_{A B}(t)$ 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)

During the operation, either of $D_1$ and $D_2$ be in forward bias. Also $R_1$ and $R_2$ are different, so output across $R$ will have different peaks.
