The resistance of a metal is given by R = V/I, where V is potential difference and I is the current. In a circuit, the potential difference across resistance is V = (8 +- 0.5) V and current in resistance, the potential difference across resistance is V = (8 +- 0.5) V and current in resistance The resistance of a metal is given by R = V/I where V is potential difference and I is the current.
