A SIMPLE explanation of a MOSFET Transistor. We go over the basics and working principle of a MOSFET Transistor, including n channel and p channel MOSFETs. You can learn more about MOSFET Transistors here: electrical4u.com/mosfet-working-principle-of-p-channel-n-channel-mosfet

MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor. The mosfet is a capacitor operated transistor device. The capacitor plays an essential role for operating a MOSFET. We also call the device as Insulated Gate Field Effect Transistor (IGFET) or Metal Insulator Field Effect Transistor (MIFET). Why we call so we will understand when we look into the constructional features of this transistor device. We must take a look into the construction of MOSFET while going through the working principle of mosfet. Construction-wise we can categorise the device into four types.

P – Channel Enhancement MOSFET
N – Channel Enhancement MOSFET
P – Channel Depletion MOSFET
N – Channel Depletion MOSFET
