The resistance of a conductor is

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 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.

The specific resistance of a conductor increases with:

Assertion : Current versus potential difference (i-V) graph for a conductor at two different temperatures T_(1) and T_(2) is shown in figure. Hence T_(1)gt T_(2) . Reason : Resistance of a conductor increases with rise in temperature.

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

Assertion (A) : The resistivity of conductor increases with the increasing of temperature. Reason (R): The resistivity is the reciprocal of the conductivity.

The resistance of a conductor depends on its
