# Find the current through a complicated circuit

• Jaccobtw
In summary: Much appreciated.In summary, the circuit has an overlapping path and the current doesn't flow in one of the two paths in the middle.

Nice, but can you give the answer you got for completeness of this thread?
Highly doubtful.

OP has a (bad) habit of not giving feedback on his/her final solutions.

The OP's trick solves this as does solving the set of current-voltage equations but is there any other way to solve for the net resistance between any two nodes without assuming anything about currents?

You mean Kirchhoff's laws? Your spice simulator does it that way.

I used Kirchhoff's laws to get equations for the currents but I meant rules like adding resistors in series and parallel. Are there special rules if they are mixed series and parallel? I suspect not.

No, the rules are simple. Either they are in series or not, either they are in parallel or not. Sometimes it's sort of an iterative process. Other times it just can't be simplified down to one resistor (like T and π sections).
