Resistivity of a given conductor depends on (A) temperature (B) Length of conductor (C) area of cross-section (D) shape of the conductor

The resistance of a conductor depends on its

Resistivity of a conductor of length l and cross - section A is rho . If its length is doubled and area of cross-section is halved, then its new resistivity will be .

A stready current i is flowing through a conductor of uniform cross-section. Any segment of the conductor has

The resistance of a metallic conductor increases with temperature due to.

The resistance of a straight conductor does not depend on its

Resistance of a conductor increases with the rise of temperature, because

State the factors affecting the resistance of a conductor.

On increasing the temperature of a conductor, its resistance increases because

The current density is defined as the current flowing per unit area of cross section of the conductor. Its direction is

Resistance of a conductor of length l and area of cross-section A is R. If its length is doubled and area of cross-section is halved, then find its new resistance.
