This video discusses how to measure the ESR (equivalent series resistance) of a capacitor using an oscilloscope and function generator.  All of the capacitors tested in this video were 220uF electrolytic caps.  In reality, the resistance in the plates of a dried out electrolytic capacitor can't be modeled as a simple series resistor, but for the purposes of identifying good from bad, this simplification works fine. In the video, I show the ESR meter that I made in 2006.  The video for that is here:
