Its function is to remove charges from its junction with the base. The section on the other side that collects the charges is called the collector. ( ii), the emitter ( n-type) of npn transistor has a forward bias and supplies free electrons to its junction with the base. ( i), the emitter ( p-type) of pnp transistor is forward biased and supplies hole charges to its junction with the base.
base so that it can supply a large number of *majority carriers. The emitter is always forward biased w.r.t. The section on one side that supplies charge carriers (electrons or holes) is called the emitter. The middle section is called the base and forms two junctions between the emitter and collector. The section on one side is the emitter and the section on the opposite side is the collector. A transistor ( pnp or npn) has three sections of doped semiconductors.
