In this tutorial, using some animation, Josh explains how a MOSFET works. These Metal Oxide Semiconductor Field Effect Transistors are strangely straightforward in their operation but the logical leap to create them, and the way they have changed the way the world works is amazing. While there are different types of Field Effect Transistors (FETs), the MOSFET is a great example of how a field effect transistor works in general. He also briefly touches on how a Field Effect Transistor is physically made.
