How Transistors Work in an Electronic Circuit

Video Transcript

Hello! This is Ross on behalf of expertvillage.com. This is a transistor. Use them in amplifiers as a matter of fact, computer chips, use transistors in them for their ones and zeros where the way up but the transistor creates a amplifier because what happen in this is a schematic symbol, there are three connection to it. This is what is called an NPN transistor based upon its construction it is a semiconductor meaning that it does not conduct and it is not an insulator either, but it can be varied based upon the voltage to the base. So more of voltage the more output. So we have a small signal coming in you will amplify that signal and you can put different components to determine how much it will amplify it. Transistor, this is a big one, by the time she will see the little ones this is a big one they can handle a lot more current so that we will get more amplification out of it.
