What Is a Transistor? (Definition, How It Works, Example) | Built In
A transistor is a device that controls an electrical current by acting as an amplifier or a switch. As an amplifier, a transistor can increase the electrical output, even if the input is small. As a switch, a transistor can alternate between ‘on’ and ‘off’ phases to manage the electrical current. These abilities have made transistors ...
How Transistors Work – A Simple Explanation - Build Electronic Circuits
2021年3月17日 · In this hands-on guide, you’ll learn how transistors work so that you can use them in your next circuit. And it’s actually pretty easy, once you learn the basics. I’ll focus on the two most common transistors here; the BJT and the MOSFET. The transistor works like an electronic switch. It can turn a current ON and OFF.
Transistors: What Are They and How Do They Work? - ThoughtCo
2018年1月6日 · 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.
