Transistor

A transistor is a tiny electronic device that acts like a switch or amplifier for electrical signals. It has three parts: the emitter, base, and collector. By controlling the current that flows through the base, a small input can manage a larger output, allowing it to turn devices on or off and amplify signals. Transistors are fundamental components in modern technology, found in everything from computers and smartphones to televisions, enabling them to process information and perform various tasks efficiently. Their invention helped usher in the digital age, replacing larger vacuum tubes with compact, reliable alternatives.
