Write a complete set of mesh equations for the circuit.

NOTE to Grader: The students only had to write the equations. They did not have to simplify or solve them.

6 I₁ + 12 I₁ - 12 I₃ + 10 I₁ - 10 I₂ = 0

28 I₁ - 10 I₂ - 12 I₃ = 0 (Eq. 1)

KVL around mesh 2.

10 I₂ - 10 I₁ + 3 I₂ - 3 I₃ - 12 + 4 I₂ - 110 = 0

- 10 I₁ + 17 I₂ - 3 I₃ = 122 (Eq. 2)

KVL around mesh 3.

12 I₃ - 12 I₁ + 70 + 2 I₃ + 12 + 3 I₃ - 3 I₂ = 0

- 12 I₁ - 3 I₂ + 17 I₃ = - 82 (Eq. 3)

I₁ = 2 A

I₂ = 8 A

I₃ = - 2 A
