The opposition an electrical conductor offers to the flow of current through itself is defined as its electrical resistance.Its formula can be given by Ohm's law as
R=V/I
where V is the voltage across the conductor and I is the current passing through it.
Its SI unit is Ohm(Ω) and 1Ω is defined as the resistance of the conductor when a potential difference of 1V causes a current of 1A to flow through it.
