Tutorial: Electrical impedance made easy - Part 1 (2011x14)

Air date: Jun 08, 2011

This is the first video of a short series in which I discuss the basics of electrical impedance from a practical standpoint. In this video, I show how a simple LED power supply circuit can be made more efficient by replacing a resistor with a capacitor. I describe the difference between resistance, reactance, and impedance.
