Question

In determining short circuit impedance parameters, among V1, V2, I1, I2, which of the following are dependent variables?

(a) V1 and V2

(b) I1 and I2

(c) V1 and I2

(d) I1 and V2

This question was addressed to me in my homework.

My query is from Short Circuit Admittance(Y) Parameters in chapter Two-Port Networks of Network Theory

Answer 1

The correct answer is (b) I1 and I2

The explanation is: In determining short circuit impedance parameters, among V1, V2, I1, I2; I1 and I2 are dependent variables and V1, V2 are independent variables i.e., dependent variables depend on independent variables.
