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

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of electronic switch used in devices like computers and smartphones. It controls the flow of electrical current between two terminals (called drain and source) using a third terminal called the gate. By applying a voltage to the gate, it creates an electric field that either allows or blocks current flow, effectively turning the device on or off. This ability to switch rapidly and precisely makes MOSFETs fundamental components in modern electronics, enabling complex circuits and efficient power management.
