Exercise 3:
Hint:
There are two non-trivial nodes; I choose labels V₁and V₂ from left to right. The nodal equation for the node on the far left is then:
-1  + V₁/3 + (V₁ - V₂) = 0.

Write down the remaining nodal equation and solve for V₁ and V₂. You may find a Linear Algebra Solver to be useful in finding the final answer.

Ans:
i₁ = -0.5 A; i₂ = -0.5 A

Exercise S3.1a:
Hint:
The nodal equation is
- 2 + V₁/4 + (V₁ + 10)/2 = 0.

Ans:
3 A

Exercise S3.2a:
Hint:
The nodal equation is
- 6 + (V₁ - 18)/3 + V₁/6 - 3 = 0.

Ans:
30 V
