Resistance of a conductor depends on: (a) Length of a conductor. Resistance of a conductor is directly proportional to the length of a conductor. If length increases resistance will also increase. (b) Area of cross section of a conductor. The resistance of a conductor is inversely proportional to the area of the cross section of a conductor. (c) Effect of material of a conductor. The resistance of a conductor also depends on the material of a conductor. E.g. The resistance of nichrome wire is 60 times more than that of copper wire as nichrome has high electrical resistance. (d) Effect of temperature. The resistance of all pure metals increases on increasing the temperature and decreases on decreasing the temperature.
