Q. 54.7( 13 Votes )

How does the resistance of a conductor depend on :

(a) length of the conductor?

(b) area of cross-section of the conductor?

(c) temperature of the conductor?

Class 10th Lakhmir Singh & Manjit Kaur - Physics 1. Electricity

Answer :

a) Resistance of a conductor is directly propotional to the length of conductor.

b) Resistance of a conductor is inversely proportional to the area of cross section of the conductor.

c) Resistance of a conductor depends upon the nature of the material of the conductor. Resistance of a conductor increases on raising the temperature and decreases on lowering the temperature.
