Q. The level of doping in a semiconductor affects its resistance, the more heavily doped layers having the _ resistance.

A
Lowest
B
Highest
C
Moderate
D
None of these
Solution:

The level of doping in a semiconductor affects its resistance, the more heavily doped layers having the lowest resistance. … It is necessary, because of the depth of this area to move the charge carriers (electrons and holes) as quickly as possible to give the photodiode a fast response to changes in light level.
