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 ... WebAn NPN transistor receives positive voltage at the collector terminal. This positive voltage to the collector allows current to flow across from the collector to emitter, given that there is a sufficient base current to turn the transistor on. PNP Transistor A PNP transistor receives positive voltage at the emitter terminal. shunterproductions social blade https://rodamascrane.com
