A cylindrical bar of silicon has a radius of 4mmand a length of 8 cm. If a voltage of 5 V is applied between the ends of the bar and μe = 0.13 (m2/V.s), μh = 0 05 (m2/V _ s), Ne = 1.5 x 1016 electrons/m3, and Nh = Ne, find
(a) The conductivity of silicon,
(b) The current I flowing in the bar,
(c) The drift velocities Ue and uh,
(d) The resistance of the bar, and
(e) The power dissipated in the bar.
