Question

In two-port networks the parameter g22 is called _________

(a) Short circuit input impedance

(b) Short circuit current ratio

(c) Open circuit  voltage ratio

(d) Open circuit input admittance

This question was posed to me in an interview for internship.

This question is from Inverse Hybrid (g) Parameter topic in chapter Two-Port Networks of Network Theory

Answer 1

Right choice is (b) Short circuit current ratio

To explain: We know that, g22 = \(\frac{V_2}{I_2}\), when V1 = 0.

Since the primary voltage terminal is short circuited and the ratio of the voltage and current in second loop is measured, therefore the parameter g22 is called as Short circuit current ratio.
