Question

Which units are given for the temperature coefficient of resistivity?

Options

• Metre per second

• Ohm or volt

• Per degree Celsius or per kelvin

• Coulomb per second

Answer 1

The temperature coefficient of resistivity is measured per degree of temperature change. Its units are per degree Celsius or per kelvin, written as \(^{\circ}\mathrm{C}^{-1}\) or \(\mathrm{K}^{-1}\).
