1.	For the circuit given below, the value of the hybrid parameter h22 is ___________(a) 0.2 Ω(b) 0.5 Ω(c) 0.1 Ω(d) 0.3 ΩI had been asked this question in an interview for internship.This is a very interesting question from Hybrid (h) Parameter in division Two-Port Networks of Network Theory
Answer» Correct answer is (a) 0.2 Ω To explain I would SAY: Hybrid parameter H22 is given by, h22 = \(\frac{I_2}{V_2}\), when I1 = 0. Therefore short CIRCUITING the terminal X-X’ we get, V1 = IA × 10 IA = \(\frac{I_2}{2}\) V2 = IB × 10 IB = \(\frac{I_2}{2}\) From the above 4 equations, we get, ∴ \(\frac{I_2}{V_2}= \frac{I_2×2}{I_2×10}\) = 0.2 Hence h22 = 0.2 Ω.
