Web1. Emitter – It is left hand section (or region) of the transistor and its main function is to supply majority charge carriers (electrons in case of NPN transistors and holes in case of P-N-P transistors) to the base. The emitter is always forward biased w.r.t. base so that it is able to supply majority charge carriers to the base. The emitter is heavily doped so that it … Webforward bias the base-emitter junction then the current vi IB =0 and thus the transistor is in the cutoff region and IC =0.
