Semiconductor Electronics question

2013 · Q143

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1
One way in which the operation of a n-p-n transistor differs from that of a p-n-p
  1. A
    The emitter junction injects minority carries into the base region of the p-n-p
  2. B
    The emitter injects holes into the base of the p-n-p and electrons into the base region of n-p-n
  3. C
    The emitter injects holes into the base of n-p-n
  4. D
    The emitter junction is reversed biased in n-p-n
View written solutionFree

Correct answer: B

In p-n-p transistor holes are injected into the base while electrons are injected into the base of n-p-n transistor. Emitter-base junction is forward biased.
