Problem

Consider the circuit shown, formed by two triangles of resistors sharing a common base. Resistors

AB=10\,\Omega

BC=20\,\Omega

AD=5\,\Omega

DC=10\,\Omega

, and the common base

BD

has a resistor of

15\,\Omega

. A battery is connected across terminals

A

and

C

. Calculate the equivalent resistance of this network.
