Transistors are semiconductor devices that can amplify or switch electronic signals and electrical power. They are fundamental building blocks of modern electronic devices, such as computers, smartphones, and televisions. Transistors have revolutionized the field of electronics by enabling the miniaturization of circuits and increasing their efficiency. They come in various types, including bipolar junction transistors (BJTs) and field-effect transistors (FETs), each with its own unique characteristics and applications.
