new cell

Randy,

It may be the stuff that I am using;  PLJ (Pure Lemon Juice).

But it's not so pure when you read the contents.

Lemon Juice (80%)
Vitamin C
Natural Lemon flavour
Lemon oil
Preservative (Sulphur Dioxide)


I have made up a series of dilutions.  As my little test cell holds 700 cc I am using 1,  2,  4  and 8 cc PLJ to produce 1, 2, 4, and 8 % mixes.
By keeping the mixes in separate jars I can try different plate configuration using the same strength mix and get a good set of current draw figures for each.

I have obtained some lab grade Citric acid,  and will re-run the tests with the same strength mixes but using the acid instead of PLJ.

Just need to get around to doing it.

Here is how I see crb's cell in +nnnn-nnnn+ configuration.  Is this correct ?

[crb]

Yes, that is how it is configured except -nnnn+nnnn-
When I ran the cell the last time, the the current draw went back down
to about 22 amps.  Tried the power resistor,
That will take more figerin!!
When I hook it up, the way I want it, It only feeds it about 5 amps.
It is a sliding clamp design type of resistor, when I adjust it to get around 17-20 amps,
it starts getting pretty warm over 200 degrees F.  Not sure on how hot to let it get.
 
I didn't notice any fir balls in my lemon juice.
Maybe it's the pulp in the mix?

Manta,
I'll try to be more exact on the voltage checks.
