Temperature effect on resistivity of metals or conductors, semiconductors and insulators

As the resistivity of a material is given as

ρ=m/ne2t

This shows that the resistivity is related to the number density n of free electrons in the material and relaxation time t. The variation of resistivity of material with temperature is different in different materials and it is discussed below: Continue reading “Temperature effect on resistivity of metals or conductors, semiconductors and insulators”
