In a typical n-p-n transistor,the doping concentrations in emitter,base & collector regions are CE,C& Cc respectively. These satisfy the relation:-
  • a)
    CE>Cc>CB
  • b)
     CE> CB> CCC
  • c)
    CC>CB>CE
  • d)
    CE= CC> CB
Correct answer is option 'A'. Can you explain this answer?

And collector regions are as follows:

- The emitter region is heavily doped with a high concentration of electrons or n-type doping.
- The base region is lightly doped with a lower concentration of electrons or p-type doping.
- The collector region is moderately doped with a higher concentration of electrons or n-type doping compared to the base region.
