AIPMT MAINS 2010 Physics Transistors MCQ Question
Type: MCQ-conceptual-Medium-Class 12
For transistor action
(a) Base, emitter and collector regions should have similar size and doping concentrations.
(b) The base region must be very thin and lightly doped.
(c) The emitter-base junction is forward biased and base-collector junction is reverse biased.
(d) Both the emitter-base junction as well as the base collector junction are forward biased.
Which one of the following pairs of statements is correct?
A
(d), (a)
B
(a), (b)
C
(b), (c)
D
(c), (d)
Correct Answer
Option C
Detailed Explanation
For proper transistor action, the emitter-base junction should be forward biased and the base-collector junction should be reverse biased. The base must be thin and lightly doped.
