Twelve wires each having a resistance of are connected to form a cubical network. A battery of 10 V and negligible internal resistance is connected across the diagonally opposite corners of this network. Determine its equivalent resistance and the current along each edge of the cube.
The resistance of the wire is given
and the battery is
Now, arranging the 12 wires each of resistance to form a cubical network.
So, Applying loop rule to
Now, the current along each edge of the cube is given as ;
