The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated by measuring the current present in the circuit (in series) and the voltage across the wire (in parallel). These measurements are then applied to this formula: Gradient = resistance V = I x R The other ways of writing Ohm's Law are: R = V/I or I = V/R Ohm's Law It is also relevant to know of Ohm's Law, which states that the current through a metallic conductor (e...
