A voltage V = 4 sin t is applied to the terminals A and B of the circuit shown in figure. The diodes are assumed to be ideal. The impedance offered by the circuit across the terminals A and B in kilo-ohms is—
-
- 5
- 20
- 10
- None of these
Correct Option: C
The given circuit (i.e., fig-1)
for the first half cycle equivalent circuit is given by (i.e., fig-2)
for the second half cycle the equivalent circuit is given by (i.e., fig-3)
Hence alternative (C) is the correct choice.
