The conductivity of the emitter region of a BJT is kept

Home » Physical Electronics Devices and ICs » Physical electronics devices and ics miscellaneous » Question

The conductivity of the emitter region of a BJT is kept—

1. Same as that of base region
2. Much larger than that of base region
3. Same as that of collector region
4. Much smaller than that of base region

Correct Option: C

The conductivity of the Emitter region of a BJT kept much larger than that of base region because the main function of emitter is to emit the charge carriers (i.e. electrons or holes). So for achieving this conductivity of emitter region of a BJT kept much larger than that of base and collector region.
