In two-port networks the parameter g11 is called _________(a) Short ci

1.	In two-port networks the parameter g11 is called _________(a) Short circuit input impedance(b) Short circuit current ratio(c) Open circuitvoltage ratio(d) Open circuit input admittanceI have been asked this question in exam.My question is taken from Inverse Hybrid (g) Parameter in portion Two-Port Networks of Network Theory
Answer» The CORRECT answer is (d) Open CIRCUIT input admittance Explanation: We know that, g11 = \(\frac{I_1}{V_1}\), when I2 = 0. Since the second voltage TERMINAL is short CIRCUITED when the ratio of the current and voltage is measured, therefore the PARAMETER g11 is called as Open circuit input admittance.
