What is a Transistor? How do Transistors Work? What is a Transistor? A transistor is a semiconductor that controls voltage or current flow in electronic signals and it amplifies and acts as a switch for them. Transistor consists of three layers each of which can carry a current. A transistor is a semiconductor device that amplifies or switches electronic signals and power. Learn about its structure, types, symbols, terminals, and configurations with examples and diagrams. A transistor is an electronic semiconductor device that is used in the circuit to control, regulate and amplify electrical voltage or current signals. Nowadays, silicon is predominantly used as the material for the construction of transistors . Understanding transistors, their types, transistor symbols, working operation is essential for electrical engineers to design modern electronic systems. What is Transistor ? A transistor is an electronic device that controls the flow of current. A Transistor has three terminals known as Base, Emitter and Collector.
