The resistance of a conductor increases with

Assertion: The resistance of a conductor decreases with increase in cross sectional area. Reason: On increasing the cross sectional area of a conductor, more current will flow through the conductor.

Assertion: The resistance of a conductor decreases with increase in cross sectional area. Reason: On increasing the cross sectional area of a conductor, more current will flow through the conductor.

The specific resistance of a conductor increases with Increase in temperature:

The specific resistance of a conductor increases with Decrease in length

Why the resistance of the conductor increases with rise in temperature.

The specific resistance of a conductor increases with Increase in cross-sectional area..

The variation of resistance of a metallic conductor with temperature is shown in figure. (i) Calculate the temperature coefficient of resistance from the graph. (ii) State why the resistance of the conductor increases with the rise in temperature.
