Question

the temperature of the resistance is increasing when it is connected to a battery then which of the following remains unchanged

Answer 1

Resistivity? Is this answer correct?

Answer 2

Answer:

The correct answer is number of  free electrons.

Explanation:

The number of free electrons present can be defined as when electrons are attached to atom.

A particular molecule or ion which moves freely within the magnetic field is phenomenon created by electrons. During the relaxation time of resistance, resistivity and drift velocity the time depends on the temperature which is normally present.

We can conclude that, the free electrons that are present in a conductor will stay in different kind of variant due to causes of the change in the temperature.
