Twelve identical wires each of resistance `6 Omega` are arranged to from a skelence cube. A current of `40 m A` is led cube at the current and out at the diagonally opposite corner. Calculate the potential difference development across these current and the effective resistance of the network

Answer

`0.2 V`

Explanation

Follow example `10` the effective resistance between two two point , which are diagonally opposite cornes of a skellon cube of `12 ` wires
`= 5 r//6 = 5 xx 6//6 = 5 Omega`
pot diff developed = resistance `x` current
`5 xx (40 xx 10^(-3)) = 0.2 V`
