How does the npn transistor work
WebJan 6, 2024 · A transistor is an electronic component used in a circuit to control a large amount of current or voltage with a small amount of voltage or current. This means that it can be used to amplify or switch (rectify) electrical signals or power, allowing it to be used in a wide array of electronic devices. It does so by sandwiching one semiconductor ... 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.

WebThe layers of an NPN transistor must have the proper voltage connected across them. The voltage of the base must be more positive than that of the emitter. The voltage of the collector, in turn, must be more positive than that of the base. The voltages are supplied by a battery or some other source of direct current. The emitter supplies electrons.

WebDec 19, 2016 · A PNP transistor will “turn on” when you have a small current running from emitter to base of the transistor. When I say “turn on”, I mean that the transistor will open up a channel between emitter and collector. And this channel can carry a much larger current. http://www.learningaboutelectronics.com/Articles/Difference-between-a-NPN-and-a-PNP-transistor
