The MOSFET is a three-terminal device that uses two metal electrodes, the source and the drain, and one semiconductor electrode, the gate. It is the most widely used type of transistor, thanks to its low cost, small size, and low power consumption.
The MOSFET works by controlling the flow of electrons between the source and drains with the gate.
When a voltage is applied to the gate, it attracts electrons from the source, allowing current to flow from the source to the drain.
The MOSFET is said to be in an “ON” state. When the voltage is removed from the gate, the electrons are repelled, and the current ceases to flow. The MOSFET is then said to be in a “OFF” state.
