How does a MOSFET control output current?

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) controls output current by using an electric field to regulate the flow of charge carriers (electrons or holes) between its source and drain terminals. When a voltage is applied to the gate terminal, it creates an electric field that alters the conductivity of the channel between the source and drain, allowing or blocking the flow of current. The amount of current that flows is proportional to the gate voltage, enabling precise control over the output current in various applications like switching and amplification.
