Question

how resistivity of metal related to temprature.​

Answer 1

Answer:

The general rule is resistivity increases with increasing temperature in conductors and decreases with increasing temperature in insulators. ... For some materials, resistivity is a linear function of temperature. ρ = ρ0(1 + α(T − T0)) The resistivity of a conductor increases with temperature

Answer 2

Answer:

When the temperature increases the vibrations of the metal ions in the lattice structure increases. ... This means that the resistivity of the metal increases and thus current flow in the metal is decreased. The resistivity increases means that the conductivity of the material decreases
