That is correct. But is is not voltage per se, but voltage gradient. That is if you double the voltage and double the spacing, then nothing changes as far as ion velocities is concerned since voltage gradient is unchanged. > > As a matter of curiosity, how does one keep current low at high > voltages? Distance? If you change the distance to restore the current, then the gradient does not change, all that happens is that you have more liquid between the electrodes, which is not necessarily bad.. > Pulse width control? > ..or is it low current 'density' from distance and very large electrodes? > Oh, re-reading...that's prolly it. ["All the water and 5 1/2 inches"] With HVAC the voltage is so high and the ions move so fast away from the electrode you are no longer limited to the 1mA per square inch, instead the current densities are closer to 1 to 5 amps per square inch. The drop is maintained by allowing only a very small part of the electrode to be in contact with the water, typically 1/10 inch of 14 guage wire with from 20 to 100 mA of current.
