As we learnt in

Transistor -

Three layered semiconducting device .

NPN or PNP

- wherein

1.    Emitter is heavily doped

2.    collector is moderately doped .

3.    Base is lightly doped & very thin

 

 In a transistor 

Emitter is heavily doped collector is moderately doped. & Based is lightly doped.

Correct option is 1.

 


Option 1)

emitter

This is the correct option.

Option 2)

base

This is an incorrect option.

Option 3)

collector

This is an incorrect option.

Option 4)

can be any of the above three.

This is an incorrect option.
