Click here to go Practice Test section on this topic namely Electrical Property.
But if you want to read this topic first and then practice it then read it carefully. The Multiple Choice Questions (MCQ) based on Electrical Property are given below:
PART - V
1) For p-type semiconductor majority charge carrier is
Correct Answer is "B"
For p-type semiconductor, the majority charge carrier is a hole
2) For an n-type semiconductor, the Fermi level located
Correct Answer is "D"
For an n-type semiconductor, the Fermi level located in the band gap just below the bottom of the conduction band
3) For a p-type semiconductor, the Fermi level located
Correct Answer is "B"
For a p-type semiconductor, the Fermi level located in the band gap just above the top of the valence band
4) For extrinsic semiconductor the host material have total impurity content in the order of
Correct Answer is "D"
For extrinsic semiconductor, the host material have total impurity content in the order of 10-7
5) At a particular temperature carrier concentration of Ge is _____ that of Si.
Correct Answer is "A"
At a particular temperature carrier concentration of Ge is greater than that of Si due to the smaller bandgap of Ge than Si.

Correct Answer is "C"
N-type germanium is obtained on doping intrinsic germanium by phosphorus
9) Depletion region is a zone which contains
Correct Answer is "D"
The depletion region is a zone which contains neither electrons nor holes
10) In a semiconductor diode arrow represents
Correct Answer is "A"
In a semiconductor, the diode arrow represents P-type material
