A cylindrical wire of silicon has a radius of 1 mm and a length of8 cm. If a voltage of 5V is applied between the ends of the bar andμe = .11 m2/Vs, μh = .04m2/Vs, Ne = 1020electrons/m3 and Nh=Ne find the following:
A) The conductivity of silicon
B) The current I flowing in the bar
C) The drift velocity ue and uh
ue = -μeE
uh = -μhE
D) The resistance of the wire
E) The power dissipated in the wire
