WebJan 2, 2024 · NPN Transistors are three-terminal, three-layer devices that can function as either amplifiers or electronic switches. In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN ( N egative- P ositive- N egative) configuration and a PNP ( P ositive- N egative- P ositive) configuration. WebJun 2, 2024 · In a pnp transistor, the emitter is made up of p region The emitter provides the majority charge carriers, which are holes. Hence in pnp transistors, majority carriers are holes. In npn transistors majority carriers are electrons. Download Solution PDF Latest NTPC Diploma Trainee Updates Last updated on Mar 30, 2024

There are two way of bringing transistor in saturation mode: 1)Use of Rc resistor: we can calculate max current (Ic) by assuming Vce = 0. Ic (max)= Vcc/Rc. you can find corresponding base current (Ib) = Ic/ (beta). WebOct 8, 2015 · Now your assumption about the emitter being connected to a P region, the base to a N region and the collector to a P region is correct. And keep in mind that a Si atom has 4 valence electrons and that hole concentration will be in the order: emitter > collector > base and reverse for electron concentration.The calculations are quite easy to do. sidemen scary games
