For transistor action, which of the following statements are correct?
A. Base, Emitter and Collector region have similar size and doping concentrations.
B. The base must be very thin and lightly doped.
C. The emitter junction is forward biased and the collector junction is reverse biased.
D. Both emitter and collector junction all forward biased.
Choose the correct answer from the options given below:
- A A and B
- B B and C
- C C and D
- D A and D
Answer & Solution
Correct Answer
(B) B and C
Step-by-step Solution
Detailed explanation
Statement B is correct: The base is kept thin and lightly doped so that charge carriers can easily pass from the emitter to the collector with minimal recombination. Statement C is correct: For normal transistor action (active region), the emitter-base junction must be forward…
