1. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. Find the value of Y₁₁.
A. 1
B. -1
C. 2
D. -2
Answer: A
Clarification: Y₁₁ = Z₂₂/∆z and ∆z=3-2=1 and Z₂₂ = 1. So on substituting we get Y₁₁ = 1/1 = 1.

2. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. Find the value of Y₁₂.
A. -2
B. 2
C. -1
D. 1
Answer: C
Clarification: Y₁₂ = -Z₁₂/∆z and ∆z=3-2=1 and Z₁₂ = 1. So on substituting we get Y₁₂=-1/1=-1.

3. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. Find the value of Y₂₁.
A. 2
B. -2
C. 1
D. -1
Answer: B
Clarification: We have the relation Y₂₁=-Z₂₁/∆z. ∆z=3-2=1 and given Z₂₁ = 2. On substituting we get Y₂₁=-2/1=-2.

4. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. Find the value of Y₂₂.
A. 1
B. 2
C. 3
D. 4
Answer: C
Clarification: The relation between Y₂₂ and Z₁₁ is Y₂₂= Z₁₁/∆z and ∆z=3-2=1 and given Z₁₁ = 3. On substituting we get Y₂₂ = 3/1 = 3.

5. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. What is the value ∆y?
A. 0
B. 1
C. 2
D. 3
Answer: B
Clarification: ∆y is the determinant of y parameters. The value ∆y is (Y₁₁)(Y₂₂)-(Y₁₂)(Y₂₁). On substituting the values we get ∆y = (1)(3)-(-2)(-1)=1.

6. For the given information Z₁₁ = 3, Z₁₂ = 1, Z₂₁ = 2, Z₂₂ = 1. What is the product of ∆y and ∆z is?
A. 3
B. 2
C. 1
D. 0
Answer: C
Clarification: ∆y is the determinant of y parameters and ∆z is the determinant of z parameters. And we obtained ∆y = 1 and ∆z = 1. So their product = (1) (1) = 1.

7. The relation between Z₁₁ and Y parameters is?
A. Z₁₁ = Y₂₂/∆y
B. Z₁₁ = -Y₂₂/∆y
C. Z₁₁ = Y₁₂/∆y
D. Z₁₁ = (-Y₁₂)/∆y
Answer: A
Clarification: V₁=(Y₂₂/∆y)I₁-(Y₁₂/∆y)I₂. The relation between Z₁₁ and Y parameters is Z₁₁ = Y₂₂/∆y.

8. The relation between Z₁₂ and Y parameters is?
A. Z₁₂ = Y₁₂/∆y
B. Z₁₂ = (-Y₁₂)/∆y
C. Z₁₂ = (-Y₂₂)/∆y
D. Z₁₂ = Y₂₂/∆y
Answer: B
Clarification: V₁=(Y₂₂/∆y)I₁-(Y₁₂/∆y)I₂. The relation between Z₁₂ and Y parameters is Z₁₂ = (-Y₁₂)/∆y.

9. The relation between Z₂₁ and Y parameters is?
A. Z₂₁ = Y₂₁/∆y
B. Z₂₁ = Y₁₂/∆y
C. Z₂₁ = (-Y₂₁)/∆y
D. Z₂₁ = (-Y₁₂)/∆y
Answer: C
Clarification: V₂=(-Y₂₁/∆y)I₁+(Y₁₁/∆y)I₂. The relation between Z₂₁ and Y parameters is Z₂₁ = (-Y₂₁)/∆y.

10. The relation between Z₂₂ and Y parameters is?
A. Z₂₂ = (-Y₁₁)/∆y
B. Z₂₂ = Y₂₁/∆y
C. Z₂₂ = (-Y₂₁)/∆y
D. Z₂₂ = Y₁₁/∆y
Answer: D
Clarification: V₂=(-Y₂₁/∆y)I₁+(Y₁₁/∆y)I₂. The relation between Z₂₂ and Y parameters is Z₂₂ = Y₁₁/∆y.
