[quote="my77gmc"]aside from that has anyone stuck a meter on their water cell and measured capacitance?
i have...do it urself and post ur results here, just for curiosities sake.
OK, Here are some Very Carefully tested results on two cells.
(Plate Sizes on each are about 2.5 by 5.5 inches.)
Water Temp = 20 Degree
Water = Store bought Distilled water.
1) B&K 878, Universal LCR Meter
2) Sencore LC102, Capacitor/Inductor Analyzer.
Both Instruments are Calibrated and I have checked there accuracy with a "Factory bought, Standard Test Set of 3 capacitors".
** Cell 1: an 8 plate "series cell". With No water = 19.5 pF.
Leakage test at 100 VDC, using instrument 2 above = 0.28 uA.
Instrument 1: Capacitance with water and on 120 hz = Varies between 2.2 to 2.9 uF.
Instrument 1: Capacitance with water and on 1 khz = Varies between 39nF to 125 nF.
Instrument 2: Capacitance with water= average of 7.4 uf, varies somewhat also.
** Cell 2: a 12 plate "parallel cell". With No water = 245 pF.
Leakage test at 100 VDC, using instrument 2 above = 0.30 uA.
Instrument 1: Capacitance with water and on 120 hz = Varies between 147 to 155 uF.
Instrument 1: Capacitance with water and on 1 khz = Varies between 6.5 uF to 9 uF.
Instrument 2: Capacitance with water = Holds fairly stable at 0.844 FARADS.
Using Instrument 2 and Attempting to test thesecell with water in them:
a) Capacitor Leakage
b) Dielectric Absorption
c) Capacitor ESR.
Absolutely FAILED on All three tests.
So if it is a Capacitor, it doesn't act like any capacitor I know of.
And Strangely Enough, using "Instrument 1" to test Inductance an the Series Cell: it measure 20 mh on the 1 KHz test.
and it measure a Huge .879 Henries on the 120 Hz test.
So does this measurement make it an INDUCTOR of that value?
I THINK NOT!
Considerably Lower resuts on the Parallel cell. But enough is enough.
