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?
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.
