Question

The specific resistance of a conductor increases with what?

Answer 1

Temperature.... .....

Answer 2

The answer is temperature.

The greater the temperature of an object, the more kinetic energy the object has. This kinetic energy is projected as the vibrations of the atoms of that object.

"Remember that an atom has free electrons wherein the movement of these free electrons produces the the current of the object."

By increasing the temperature, thus increasing vibrations, these free electrons collide with the non-free electrons. These collisions releases the energy from the free electrons making the electrons lose energy. This causes the increase of resistance.

Increasing the size of the conductor also increases resistance wherein thinner wires have greater resistance to current.
