What is transistor and how to check in digital multimeter

What is the function of a transistor? Transistors Functions | Electronics Basics | Transistors have the function of amplifying and switching electrical signals. In the case of radio, the extremely weak signals transmitted through the air are magnified (amplified) before playing through speakers. This is the amplification action of a transistor. A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuitFor Training Purpose Call SK Computer Technologies Mb: 9444180072 / 9841925321 Website: Email: skcom2001@ map location:
