Circuit simplifications using startodelta, parallel and series transformations, seems pretty powerful. It allows one to obtain resistances a circuit that has a planar, mesh structure (the "window pane" structure). The term planar is used to describe circuits that can be drawn in a plane without the need for wires to cross one another. Circuit Magic can help you to obtain both planar and nonplanar circuits resistances.
Sample circuit. Resistors resistances are different values (not simple, Try to simplify it using startodelta, parallel and series transformationsü)
Step1. Connect node 1 and node 7 using branch with current source (current =1 amps)
Step 2. Solve circuit using Node Voltage method
Step 2. Calculate circuit resistance using Ohms Law
