In determining open 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 V2I got this question in an interview.Question is taken from Open Circuit Impedence(Z) Parameters topic in division Two-Port Networks of Network Theory

Answer»

Right answer is (a) V1 and V2

The best explanation: In determining open CIRCUIT impedance parameters, among V1, V2, I1, I2; V1 and V2 are dependent VARIABLES and I1, I2 are INDEPENDENT variables i.e., dependent variables DEPEND on independent variables.
