Resistance of Copper Wire increases with

Resistance of Copper Wire increases if the:

  1. Temperature is increased
  2. Temperature is decreased
  3. It is doped
  4. None of these

Correct answer: 1. Temperature is increased

The temperature coefficient of copper wire is positive (i.e +0.393)

This means if temperature increases by 1 degree then the resistance increases by 0.393%
