For the circuit shown in the given figure, when the voltage E is 10 V, the current i is 1 A. If the applied voltage across terminal C-D is 100 V, the short circuit current flowing through the terminal A-B will be

1. 0.1 A
2. 1 A
3. 10 A
4. 100 A^t

Correct Option: C

Using Y-parameter,
1₂ = Y₂₁. V_AB + Y₂₂. V_CD
When V_AB = E = 10_V,
I ₂ = 1_A, and V_CD = 0
then Y₂₁ = 0.1
When port 1 becomes port 2 and vice-versa,
then 1₂ = Y₂₁. V_CD + Y₂₂. V_AB
When V_AB = 0, V_CD = 100
then I₂ = 0.1 × 100 = 10_A
