Calculate the electrical resistivity and conductivity of a silicon crystal if every 10 mollion silicon atoms is replaced by an atom of indium. Given that intrinsic carrier density of silicon `= 1.5 xx 10^(16) m^(-3)`, atomic weight of silicon = 28.09, density of silicon `= 2330 "kg m"^(-3)`, mobility of electrons `(mu_(n))=0.135`, that of holes `(mu_(p))=0.018`, By how many times is the conductivity increased ?
