Understanding MOSFETs: MOSFET as a Switch (Supplemental Video)

This is a supplemental video for the blog post at motbots.com titled "Understanding MOSFETs: Key Concepts and Practical Examples".

_________________ UPDATE:_________________

UPDATE: As of 01/29/2025, it’s been brought to my attention by @RexxSchneider (YouTube) that a mistake was made on this example circuit on the website’s page titled “Understanding MOSFETs: Key Concepts and Practical Examples" (link below). THIS MISTAKE HAS BEEN CORRECTED ON THE SITE.

The mistake does not affect the making or working of the circuit in this video, but some of the resistors used here now have different values than represented on the website, so any mention of calculations here won't be the same as on the site. Also, the mention of using the multimeter has been disregarded in the updated example on the website and other information has been given. Sorry for any confusion or inconvenience. Thanks for your understanding. Enjoy 😊

P.S. I will link the updated video for the website example in the description of this video when it becomes available. Thank you.
