This looks rather daunting especially with 2 wires which cross over others. Way too many meshes for any basic method.

With the free student version of AIM-SPICE, available for download here.

It took a little less than 3 minutes to type in the netlist.

Setting up the netlist is very simple and requires no special training. SPICE didn't seem to have any trouble solving the netlist. The log file said it took "0" seconds for the program to solve it.

Cool!

Once I figured out how to use the interface, my mind was blown. I love free, useful software and this is definitely on that list.

It's actually possible to do by hand using what's called a delta-wye conversion, but I remember that configuration of resistors taking a half hour or so to simplify without calculations just to prove it could be done, and most of an afternoon to calculate. Ether's method is undeniably simpler, but in my opinion at least, nowhere near as fun
