Using circuit magic to calculate circuit resistances

Circuit simplifications using star-to-
delta, 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
non-planar circuits resistances.
Sample circuit. Resistors resistances
are different values (not simple, Try to
simplify it using star-to-delta, parallel
and series transformationsü).
