Question

In general, when the temperature of a conductor increases, its resistance
​

Answer 1

Answer:

increases (exception superconductors)

Explanation:

RT = R0(1+ alpha(delta T)

RT is the resistance at given temperature

R0 is resistance at reference temperature

delta T is difference between given T and reference T

Alpha is temperature coefficient of the conductor.

Answer 2

Answer:

For conductors, the temperature coefficients of resistance is positive; hence the resistance of the conductor is directly proportional to the temperature. So when temperature increases, the resistance of the conductor increases as well
