TransistorsA transistor is a type of semiconductor device that is commonly used as an amplifier or switch. It consists of three layers of a semiconductor material, with each layer having a different electronic charge. By applying a voltage to the transistor, the flow of electrons between the layers can be controlled, allowing the transistor to amplify or switch electrical signals. Transistors are widely used in a variety of electronic devices, such as radios, televisions, and computers, and are a key component in the operation of modern electronics.
