Why can you ignore the dependent current sources?I got -4 by:
The hybrid parameters of a circuit are given by:
V1 = h11 * i1 + h12 * V2
i2 = h21 * i1 + h22 * V2
Where:
- h11, h12, h21 and h22 are the hybrid parameters;
- V1, V2, i1 and i2 can be found in the image;
Using the definition of the hybrid parameters, i can use h11 = V1/i1 for V2 = 0.
In this situation ( for V2 = 0) we have a short circuit in the right side of the original circuit. Therefore, we can "ignore" the dependent current sources, so we just use the dependent voltage source to get the answer.
Any problems in this solution?
