It is the ability of the conductor to resist the flow of electric current through it.It depends on the nature of the conductor, its length,area of cross section of the conductor and its temperature.
Resistance is the opposition that a substance offers to the flow of electric current. When an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one Ohm.R=V/Iwhere R-resistance, V-voltage, I-current
