1. What is a MOSFET?

A MOSFET is a voltage-controlled field-effect transistor. It controls the flow of current between the source (Source, S) and drain (Drain, D) by applying a voltage to the gate (Gate, G).
2. What are the main uses of MOSFETs?

As a switch: used to quickly turn a circuit on or off.
As an amplifier: amplifies signals in analog circuits.
As a power switch in applications such as power management, motor control, inverters, etc.
3. What role does a MOSFET play in a motor?

MOSFETs are often used for functions such as speed control, direction control, and soft start/stop of motors. They can respond quickly to control signals and provide precise current control.
4. Do MOSFETs work in AC or DC?

MOSFETs can work in both DC and AC circuits, depending on the specific application requirements.
