A transistor has three zones; emitter, base and collector, and can be built two different ways, as NPN or PNP. An NPN transistor has an N doped emitter, a P-doped base followed by an N-doped collector as shown in Figure 1a) and represented schematically in Figure 1b).
NPN Transistor - Definition, Types, Construction and Working
Web945K views 4 years ago The Learning Circuit Rather than using a physical, mechanical switch, a transistor can act as an electronic switch, using signals to turn it on or off. Karen goes over what... WebSep 9, 2024 · A transistor works in two modes – saturation and cutoff. When it works as a switch, it turns off when it is in cutoff mode, since no collector current flows through it, and it turns on when working in saturation mode. Collector current is generated when an input signal is present at the base; this is when the transistor is ON. raw theraphee

WebWhen the button is pushed, the 100uA or so of base current will be sufficient to make 5mA or so of emitter current. You'll get 5V drop across the 1k, 2v across the LED, and the npn … WebThe NPN transistor is designed to pass electrons from the emitter to the collector (so conventional current flows from collector to emitter). The emitter "emits" electrons into … WebThe NPN transistor is made by placing a p-type material between two n-type materials. Likewise, the PNP transistor is made by placing an n-type material between two p-type materials. Field Effect Transistor A field-effect transistor shortly termed as FET is a voltage-controlled device, unlike BJT which is a current controlled device. rawtherapy
