1.	An type silicon bar 0.1 cm long and 100 μm in cross-sectional area has a majority carrier concentration of 5 x 10/m and the carrier mobility is 0.13 m/V- at 300k. If the charge of an electron is 1.6 x 10 coulomb, then the resistance of the bar is
Answer» Resistance of bar(R) = l = 0.1 cm, A = 100 x 10-6 m2 σ = neμn + Peμp But bar is of n type then it can be approximated to σ = neμn.
