Hello all,

How strong a current can I move though water?
Googling I have found only conductivity of salt water, but what is water's impedance?

Can I create 1 ms pulse of 500 volts and 1 A using salt water?

I want to use salt water as electrodes:
two metal electrodes submerged in two different salt water "bags", connected by some type of bio-metrial.

Any1 has information that might suggest it will work or fail?


Thanks alot
Erez

Ultrapure water specific resistance is 18 MΩcm, so you can assume it is a perfect insulator. Conductance is due to solved ions only and depends on their concentration.

Hi,

That's way I am talking of salt water. which has about 5 s/m.
But what about inductance and capticence?

and how does the impedance change at high freuqency?

Also, the issue is how FAST does ionic current can work?

Honestly, these things are addressed in any serious electrochemistry textbook. Check for example Electrochemistry by Jiri Koryta, Jiri Dvórák and Vlasta Bohácková.
