The circuit shown in figure below is equivalent to a load of—
-
-
4 Ω 3
-
8 Ω 3 - 4Ω
- 2Ω
-
Correct Option: B
The given circuit 
The load is given by ratio of voltage, V to the current, I
V = 4 (I – I1) …(i)
and
V = 2I1 + 2I …(ii)
From equation (i) and (ii):
4I – 4I1 = 2I1 + 2I
or
2I = 6I1
or
I = 3I1
or
I1 = I/3
Now,
| V = 4 |  | I - |  | = | ||
| 3 | 3 |
or
| = | Ω | ||
| I | 3 |
Hence alternative (B) is the correct choice.
