What are the effect of impurities on resistivity, Chemistry

Assignment Help:

Effect of impurities on resistivity:

A  small  percentage  of  impurities  can  result  in  substantial  increase  in  resistivity  i.e. decrease in the conductivity.

Mathematically, it can be represented as

Ρalloy = Ρmetal + YPi

Where

Palloy → resistivity of alloy.

Pmetal → resistivity of parent metal

Pi → resistivity of impurity added
