Question

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 Ω

The question was posed to me in exam.

Asked question is from Hybrid (h) Parameter in chapter Two-Port Networks of Network Theory

Answer 1

Correct choice is (a) 0.2 Ω

The explanation: 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 × 5

V2 = IA × 5

IA = I2

From the above equations, we get,

∴ \(\frac{I_2}{V_2} = \frac{I_2}{I_2×5}\) = 0.2

Hence h22 = 0.2 Ω.
