Question

Example 20.1: A potential difference 10 V is applied across the ends of the intrinsic silicon bar having
length 0:6 cm and cross-section 20 mm x 20 mm. Assuming n; = 1'5 106 electrons/m), He = 0-14 m/Vs,
and 14, = 0·05 m?/Vs, find (i) electron and hole components of the current density, (ii) total current density,
(iii) total current in the bar, (iv) conductivity and resistivity.

Answer 1

Answer:

i think that the answer is (iv)
