Question

The necessary condition in making of a junction transistor (E-emitter, B-base and C-collector)

• A. E is heavily doped, B is thin and lightly doped and C is moderately doped
• B. E and C are lightly doped and B is thick and heavily doped
• C. E and B are heavily doped and C is lightly doped
• D. E and B are lightly doped an C is heavily doped

Answer 1

The correct option is A E is heavily doped, B is thin and lightly doped and C is moderately doped

In a bipolar junction transistor, the emitter is heavily doped, base is thin and lightly doped and collector is moderately doped. This is done to ensure the presence of high emitter current and small base current. This enables to use transistor for amplifying purposes.
