A transistor is a semiconductor device that can amplify and switch electronic signals, serving as a fundamental building block in modern electronic circuits. It can control the flow of current or voltage and is crucial in devices like computers, radios, and amplifiers. Transistors can be found in two main types: bipolar junction transistors (BJTs) and field-effect transistors (FETs), each with unique operational principles.
