Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET)

A Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is a type of electronic switch used in circuits to control the flow of electricity. It has three main parts: the source, the drain, and the gate. By applying a voltage to the gate, it creates an electric field that opens or closes a tiny channel between the source and drain, allowing current to flow or stopping it. MOSFETs are widely used in computers and electronic devices because they can quickly turn on or off with minimal power, acting as fundamental building blocks for digital and analog circuits.
