    Exactly. After seeing that picture, I suspect the culprit is the dielectric inside the capacitor, as there is so much surface area tucked into that cylinder and, with age, I am sure the dielectric is more leaky than it was originally - though I am sure it's always been leaky. Still, 8 days and it only lost about half its stored charge... not bad!

    Thanks for a fun distraction tonight, @nybill and @bobjonkman! Attached is a calculation using some of the RC equations that, given the original post, estimates the resistance through which charge in the capacitor leaked over the 8 days and 1.5 hours it was sitting. Enjoy! https://chirp.cooleysekula.net/attachment/21662

    Actually, now that I see the original @nybill post I realize we can estimate the resistance in the circuit using the fact that he have us the start day of his charge and the current voltage. :-) I love this stuff.

    And you'll also need Ohm's Law, since V_0 = I_0 R will give you the voltage-current relationship at time zero, when V_0 = 64V.
