The circuit shown in the figure given below is
-
-
a voltage source with voltage r V R1 // R2 -
a voltage source with voltage r // R2 V R1 -
a current source with current r // R2 . V R1 + R2 r -
a current source with current R2 . V R1 + R2 r
-
Correct Option: D
It behaves as a current source since I0 depends on Vin and resistance only.
| I0 = | = | - | ||||
| r | R1 + R2 | r |
| η = | ||
| R1 + R2 |
I0 ∝ Vin
| I0 = | × | ||
| R1 + R2 | r |
