Junction Transistor
In a transistor, comparing the doping of emitter, base and collector, the part which is heavily doped and that which is lightly doped are respectively
Show answer and solution
Answer: (b)
- The emitter must supply many carriers, so it is heavily doped.
- The base is thin and lightly doped so that few carriers recombine there.
- The collector is moderately doped.
- So the answer is (b) emitter and base.
