## Homework Equations

KCL

KVL

V = IR

## The Attempt at a Solution

I used 4 nodes at the top, one reference node at the bottom.

I have it labeled V1, V2, V3, V4, starting from the far left -> right.

My nodal equations are:

**At v1:**

+ 7V

**At v2:**

0 = (v2-v1) / 2 + v2 / 4 + (v2 - v3) / 4

**At v3:**

(v3-v2) / 4 + v3 / 8 + (v3 - v4) / 8 = 0

At v4:

At v4:

0 = (v4-v3)/ 8 - 1mA

so we know V0 is

**v2-v3 = v0**.

I'm not sure if this is correct so far.
