depending factors of resistance
Asked by venkat | 21st May, 2013, 06:02: PM
R = rho*L/A where R is the resistance of a conductor, rho is the resistivity of the material of the conductor, L is the length of the conductor and A is the cross sectional area.
So, as you will see, the resistance of a conductor is directly proportional to the length while inversely proportional to the cross sectional area. So, resistance increases with increase in the length of conductor but decreases with increase in the cross sectional area.
