1.	In two-port networks the parameter g12 is called _________(a) Short circuit input impedance(b) Short circuit current gain(c) Open circuit reverse voltage gain(d) Open circuit output admittanceThis question was addressed to me in an interview for job.My doubt is from Inverse Hybrid (g) Parameter topic in section Two-Port Networks of Network Theory
Answer» Right option is (c) Open CIRCUIT REVERSE voltage gain Explanation: We know that, g12 = \(\frac{I_1}{I_2}\), when V1 = 0. Since the primary terminal is short circuited and the ratio of the TWO currents is MEASURED, THEREFORE the parameter g12 is called as Short circuit current ratio.
