How do impurities and temperature affect electrical resistivity of metals?
Ans:
Temperature effect on resistivity:
Any increase in temperature of a conductor increases thermal agitation of metallic ions as they vibrate about their mean positions. This reduces the mean free path and restricts the flow of electrons, hence reducing the conductivity of material and increasing its resistivity.
Ρt = Ρω [1+ α0 (t− 20)]Ρt → resistivity at temperatureΡ20 → resistivity at 200c.α0 → Coefficient of temperatureWhich is positive.
