In the simplest way I can possibly put it :
MOSFETs are tiny electronic components that regulate the flow of electricity, such as switches a device that boosts electrical signals. The drain, gate, and source are the main parts of it. A current of electricity begins at the source and ends at the drain. Like a control switch, the gate connects the source and drain. The MOSFET's layout decides whether the electric field generated by a voltage applied to the gate permits or limits current flow across the source and drain.
