Answer 1

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.
