AO #11 - MOSFETs! (Part 2 of Transistors)

Following up from Episode #10 on BJT, this episode is focused on introducing MOSFETs. It is the longest video we've done yet, coming in just over 7 and a half minutes.  

There is a basic overview of how MOSFETs work, compared to a BJT.  And something that is really important to consider:  how hot is it going to get?  So we go through how to calculate power dissipation and if you need a heat sink.

Episode 10: Transistors Part 1 of 2 (BJTs

The two most popular kinds of transistors you might use for a project are either BJTs or MOSFETs.  With so many options, it was tough to pick just a few.  In AddOhms #10, we look at NPN BJTs and how to use it as a switch.

in #11 we'll come back and cover the high current brothers:  MOSFETs. 

Transistors are electronic switches that are used to control things that would kill an Arduino, Raspberry Pi, or Beaglebone. There are two major types known as a BJT and MOSFET. This is part 1 of a two part series, which looks at BJTs first. Learn what they are and how to use them.

There's a new section just for Videos on Electronic Components.

We covered the 2n3904 in this video.  What BJTs are your favorites and why?  Leave a comment below.
