Part 2: http://www.youtube.com/watch?v=3eO1NJ6mRkU
First of a 2 part lesson explaining alternating current. Part 1 deals with the basics - period, frequency, peak values and looks at power for a square wave. Part 2 deals with RMS (root mean square) power calculations.
Thanks for making this video! The clear explanation helps me a lot in revising this complicated topic!
