Question

3. A pure silicon crystal of length (0.1m) and area
A
${10}^{ - 4} {m}^{2}$
has the mobility of electron (,) and holes
0u.) as 0.135 m/Vs and 0.048 m'/Vs. respectively.
If the voltage applied across it is 2V and the intrinsic
charge concentration is n = 1.5x10 m. then the total
current flowing through the crystal is.
