## Homework Statement

I need to write Kirchhoff rues for the following circuit. This is not for a physics class, but for a programming class. I can do that part, but I am not sure if the equations are correct.

## Homework Equations

## The Attempt at a Solution

V1-I1*R1-(I1-I2)R3-I1*R2=0

V2-(I2-I3)R5-I2*R4-(I2-I1)R3=0

V3-I3*R6-I3*R7-(I3-I2)R5=0

These neglect R8, however.

Should I also include:

V1-I1*R1-(I1-I2)R3-(I1-I2)R4-(I1-I3)R7-I1*R8=0

V2-(I2-I3)R5-(I2-I3)R7-(I2-I1)R8-(I2-I1)R2-(I2-I1)R3=0

V3-I3*R6-(I1-I3)R8-(I3-I1)R2-(I3-I2)R4-(I3-I2)R5=0

These last three equations seem really wrong. I am not sure how many currents there even are.
