Electrical Engineering Questions and Solutions Set 3
Question:-
Option (A)
h11 = 10 kΩ, h12 = 3 x 10-4, h21 = 25 x 10-6, h22 = 25 mho
Option (B)
h11 = 3 x 10-4 kΩ, h12 = 10, h21 = 25 x 10-6, h22 = 25 mho
Option (C)
h11 = 3 x 10-4 kΩ, h12 = 10, h21 = 25, h22 = 25 x 10-6 mho
Option (D)
h11 = 10 kΩ, h12 = 3 x 10-4, h21 = 25, h22 = 25 x 10-6 mho
Correct Option:
D
Question Solution:

KVL
V1=r1 I1 + βV2 ≡ h11 I1 + h12 V2
h11=r1 = 10 kΩ
h12=β = 3 x 10-4
KCL
I2= ≡ h21 I1 + h22 V2
h21=α = 25, h22 =
=25 x 10-6 mho
