The transistor is the primary building block of all microchips, including your CPU (Central Processing Unit). It is what creates the binary 0's and 1's (bits) your computer uses to communicate and deal with Boolean logic. Learn what a transistor is, how it works and its types. A transistor is a semiconductor device that transfers a weak signal and regulates and amplifies electrical signals. 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.
