I am having a real difficult time with the first part of my assignment. I need to set up 9 linear equations from this diagram.

Using Kirshoff's laws which are:

1.) The potential drop around each closed loop in the circuit board adds up to zero.

2.) (Current conservation) The current at each node is conserved: The amount of current flowing into

the node is equal to the amount of current flowing out of the node.

More info can be found here with an example for each law but I still do not understand. Maybe someone can help

Thanks, Len

Edit: The equations I am setting up are to solve i and $\displaystyle i_n$ (n=1..8)
