Question

In two-port networks the parameter h22 is called _________

(a) Short circuit input impedance

(b) Short circuit current gain

(c) Open circuit reverse voltage gain

(d) Open circuit output admittance

The question was posed to me during an internship interview.

My query is from Hybrid (h) Parameter topic in chapter Two-Port Networks of Network Theory

Answer 1

Correct option is (d) Open circuit output admittance

The explanation is: We know that, h22 = \(\frac{I_2}{V_2}\), when I1 = 0.

Since the current in the first loop is 0 when the ratio of the current and voltage in the second loop is measured, therefore the parameter h22 is called as Open circuit output admittance.
