When a PNP transistor is properly biased, the holes from the emitter

When a PNP transistor is properly biased, the holes from the emitter Correct Answer diffuse through the base into the collector region

Diagram

Working of PNP transistor:

  • PNP transistor is a current controlled device.
  • Holes are the majority carriers in the PNP transistor.
  • The emitter-base junction is connected in forward bias due to which the emitter pushes the holes in the base region.
  • Holes constitute the emitter current. These holes move into the N-type semiconductor material or base, they combined with the electrons.
  • The base of the transistor is thin a lightly doped. Hence only a few holes combined with the electrons and the remaining are moved towards the collector space charge layer. Hence develops the base current.


Therefore, when properly biased holes from emitter diffuse through the base into the collector region.
