Question

The parameters Y11, Y12, Y21, Y22 are called?

(a) Open circuit impedance parameters

(b) Short circuit admittance parameters

(c) Inverse transmission parameters

(d) Transmission parameters

This question was posed to me in a national level competition.

This intriguing question originated from Short Circuit Admittance(Y) Parameters in portion Two-Port Networks of Network Theory

Answer 1

Right answer is (b) Short circuit admittance parameters

To explain I would say: The parameters Y11, Y12, Y21, Y22 are called short circuit admittance parameters also called network functions as they are obtained by short circuiting port 1 or port 2.
