One way in which the operation of n−p−nn-p-n transistor differs from of a p−n−pp-n-p :

Options

  1. AThe emitter junction injects minority carriers into the base region of the p−n−pp-n-p
  2. BThe emitter junction injects minority carriers into the base region of the p−n−pp-n-p
  3. CThe emitter injects holes into the base of n−p−nn-p-n
  4. DThe emitter junction is reversed biased in n−p−nn-p-n

Correct answer

B. The emitter junction injects minority carriers into the base region of the p−n−pp-n-p

Step-by-step solution

The emitter injects holes into the base of the p−n−pp-n-p and electrons into the base region of n−p−nn-p-n.
