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.
