Grade 12Electric Current

is there a shortcut to find equivalent resistance between two points in 3d network which doesnt involve kirchoff laws I know the shorcuts for standard cube, octahedra, tetrahedra but say of non standard figures? (i can calculate using Kirchoff but it is time consuming)

1. There are various theorem like , mirror theorem, and white stone bridge like concepts which can be used to find equivalent resistance in some special circuits, but in general you have to use this basic principal always.
