QNEET-2023-Ph-326: NEET 2023 Physics - Class 12 NEET-2023-Ph-326 Solution: The above figure shows the circuit symbol of a transistor.…
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 n-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. (C) and (D) (A) and (D) (A) and (B) (B) and (C)
Multiple Choice Options
- A (C) and (D)
- B (A) and (D)
- C (A) and (B)
- D (B) and (C)
Step-by-Step Verified Solution
In given symbol, emitter current leave from emitter so transistor is NPN
order of doping E > C >> B
order of size C > E >> B
for active mode emitter base junction is forward bias and base-collector junction is reverse bias.
