How does a transistor work as an amplifier? How does a transistor amplify a signal? When we apply a small signal to the base of a transistor, an amplified or amplified output signal is obtained from the collector and emitter. Today, through this video, you will learn more about how a transistor works as a switch and why a transistor is used as a switch. Today, I will try to explain it to you in a very simple and easy way. If you watch my video patiently today, I hope you will be clear and know about how a transistor works as an amplifier and how a transistor amplifies a signal.
