1.	For the circuit given below, the value of the Inverse hybrid parameter g11 is ___________(a) 0.067 Ω(b) 0.025 Ω(c) 0.3 Ω(d) 0.25 ΩThe question was asked during an online exam.Origin of the question is Inverse Hybrid (g) Parameter in portion Two-Port Networks of Network Theory
Answer» Right answer is (a) 0.067 Ω The EXPLANATION is: 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 ((10\|\|10) + 10) = I1 \(\left(\left(\frac{10×10}{10+10}\right)+10\right)\) = 15I1 ∴ \(\frac{I_1}{V_1} = \frac{1}{15}\) = 0.067 Ω Hence g11 = 15 Ω.
