Directions: In the following questions, a statement of assertion (A) ...
Assertion and Reasoning
Assertion (A): The resistivity of the conductor increases with the increasing temperature.
Reason (R): The resistivity is the reciprocal of the conductivity.
Explanation
Resistivity is defined as the resistance offered by a material to the flow of electric current through it. The resistivity of the conductor increases with the increase in temperature. This happens because the temperature causes the atoms in the conductor to move around more vigorously and collide with the electrons, which obstructs the flow of current. The obstruction of the flow of current leads to an increase in resistance and hence an increase in resistivity.
On the other hand, conductivity is defined as the ability of a material to conduct electric current. It is the reciprocal of resistivity. As resistivity increases with increasing temperature, conductivity decreases. Therefore, the reason given in the statement is correct.
Conclusion
Both assertion (A) and reason (R) are true, but the reason (R) is not the correct explanation of assertion (A). The correct explanation is that an increase in temperature leads to an increase in resistivity, which causes an increase in resistance, and hence, a decrease in conductivity.
Assertion (A): The resistivity of the conductor increases with the increasing temperature.
Reason (R): The resistivity is the reciprocal of the conductivity.
