... terminals of a battery, If we increase the voltage, current will also increase so, I=V The opposition against the flow of the electrons is called the Resistance, R, of the wire. The resistance of a wire is the voltage applied to its ends, divided by the current that flows through it, or R=V/I (V/A)= ...
