The above figure shows the circuit symbol of a transistor. Select the correct statements given below: (A) The transistor has two segments of p-type semiconductor separated by a segment of -type semiconductor. (B) The emitter is of moderate size and heavily doped. (C) The central segment is thin and lightly doped. (D) The emitter base junction is reverse biased in common emitter amplifier circuit.
Options
- A(A) and (B)
- B(B) and (C)
- C(C) and (D)
- D(A) and (D)
Correct answer
B. (B) and (C)
Step-by-step solution
The given transistor represents a transistor so statement is eliminated.
Emitter is of moderate size and heavily doped and central segment is thin and lightly doped.
So, statements (B) and (C) are correct.
Emitter base junction is forward biased.
