Calculate the resistivity of n-type semiconductor from the following data, Density of holes = 5 x 1012 cm-3. Density of electrons = 8 x 1013 cm-3, mobility of conduction electron = 2.3 x 104 cm2/ V-sec and mobility of holes = 100 cm2/V-sec.
Answer: Option
Explanation:
Resistivity(r) = 
.

Thanks @Lik.

@Lik When you want to convert the cm to meter, it must be divided by 100 and not multiply.
0.29488cm x (1m/100cm).
0.29488cm x (1m/100cm).

@Psalmer Since cm is in the denominator before getting the reciprocal of it for the resistivity, you must multiply it by 100 to convert it to the meter.
