Question

A battery of 10 volt and negligible internal resistance is connected across a diagonally opposite corners of a cubical network consisting of 12 resistors each of resistance 1 ohm determine the equivalent resistance of the network and the current along each edge of the cube

Answer 1

(1/3+1/6+1/3) ohms is the equivalent resistance (R/3+R/6+R/3)

The equivalent resistance = 5/6 ohms

Current = 10/(5/6) = 60/5= 12 A
