Q1:

If a sample of germanium and a sample of silicon have the same impurity density and are kept at room temperature

A both will have equal value of resistivity

B both will have equal negative resistivity

C resistivity of germanium will be higher than that of silicon

D resistivity of silicon will be higher than that of germanium

ANS:D - resistivity of silicon will be higher than that of germanium

Resistivity of silicon is more than that of germanium.
