1. How does a MOSFET work?
When a sufficient forward voltage is applied to the gate relative to the source, a conductive channel is formed on the silicon surface under the insulating layer, allowing current to flow from the source to the drain. For an N-channel enhancement MOSFET, the channel begins to conduct when Vgs (gate-source voltage) exceeds the threshold voltage Vth; for a P-channel MOSFET, the opposite is true.

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.
