Answer 1

Right choice is (b) 0.133 Ω The best explanation: Inverse Hybrid parameter g11 is given by, g11 = \frac{I_1}{V_1} , when I2 = 0. Therefore short circuiting the terminal Y-Y’, we get, V1 = I1 ((5 || 5) + 5) = I1 \left(\left(\frac{5×5}{5+5}\right)+5\right) = 7.5I1 ∴ \frac{I_1}{V_1} = \frac{1}{7.5} = 0.133 Hence g11 = 7.5 Ω.
