Here is a bit from wiki ""Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied"" In respect of a capacitor the impedance of it is known as ESR ( Equivalent Series Resistance) and is measured in ohms, a perfect capacitor would have...

Hi Rob This is a really interesting topic and your tests have shown improvements. I am intrigued as to what effect the capacitor's internal impedance / ESR has on these fluctuations, I do understand that in high frequency switch mode power supplies it has a direct effect on the output ripple...
