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
The radius of the nucleus is related to the mass number A by : (1 )R= R 0 A 1/2 (2) R= R 0 A (3) R= R 0 A 2
