In two-port networks the parameter h11 is called _________(a) Short ci

1.	In two-port networks the parameter h11 is called _________(a) Short circuit input impedance(b) Short circuit current gain(c) Open circuit reverse voltage gain(d) Open circuit output admittanceThe question was posed to me during an online exam.I'm obligated to ask this question of Hybrid (h) Parameter topic in chapter Two-Port Networks of Network Theory
Answer» Correct choice is (a) SHORT circuit INPUT impedance Explanation: We know that, h11 = \(\frac{V_1}{I_1}\), when V2 = 0. Since the SECOND output terminal is short circuited when the ratio of the TWO voltages is measured, therefore the parameter h11 is called as Short circuit input impedance.
