MOSFET Transistor Basics & Working Principle | Electrical4U

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: www.electrical4u.com/mosfet-w...
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

If theres no positive voltage on the gate there will be no current between drain and source ....so what s the difference with bjt

The BEST explanation of a how a mosfet works by far. I watched few videos but this is the Clearest explanation. Thank you.

[@abhaysahu1722]

One of the best videos on Mosfet. So simply explained, a stuff which is not easy to understand from textbook. Crisp and to the point. Thanks for the video.

hi, correct me if i'm wrong, there should be body(substrate) terminal connected internally to source, with out this terminal mere application DC across drain and Source cannot make p- n junctions Forward bias or reverse Bias

Yes, there is a substrate terminal, and it's connected to the source. Watch it here - czcams.com/video/rkbjHNEKcRw/video.html

Electrons should flow from - Negative or Source Terminal to Drain terminal....

[@hiZarki]

yes, but current is defined in the opposite direction of electron flow. honestly I wish they would change that. so confusing

[@leroycasterline1122]

@@hiZarki I paused the video to check comments when I saw current flowing from positive to negative, having been taught that electrons flow from positive to negative some 50 years ago.
I don't understand how current (defined as the number of electrons per second as I recall) can be thought of as flowing in the opposite direction. This was called 'hole flow' back then. Can you explain?

[@PunkHippie1971]

Leroy Casterline I am confused as well because it looks as though the current is flowing through the reverse biased side.
