heathicus wroteSo when you say "current", do you mean "amperage"?
In terms of volts and amps, what is "current"?
And my personal hypothesis is that various voltages all at the same amps will result in no difference. My son's hypothesis is that it will. I haven't told him my hypothesis.
Yes, current and amperage are synonyms, electrically speaking. The unit of measure of current is the Ampere (named after an early scientist in the field), and abbrievated "Amp", or simply "A". Volts, by the way, are named in honor of Volta, a physicist.
A simple yet useful analogy for electrical circuits is fluid flow. Think of water in a pipe. The higher the pressure, the faster the water wants to flow. Electrical current is analogous to water flow rate. Any restriction in a water line tends to generate back pressure, and thus reduce the flow rate. This flow restriction is analogous to electrical resistance. And voltage is analogous to water pressure. In fact, Ohm's law states that the current between two points in a circuit is proportional to the voltage across those two points. Yup, you guessed it, the unit of measure of electrical resistance is the Ohm, so named after German physicist George Ohm.
Now given a particular flow restriction, you cannot control both the flow rate and the pressure. If you apply a given pressure, a certain flow rate will result. Conversely, if you pump water through the restriction at a given rate, a certain pressure drop will result.
In the electrical problem at hand, we are all advising you to adjust the electrical resistance of the electrolysis tank, by any of the means that JPG enumerated, so that an acceptable current results when you apply a fixed voltage from one of your available voltage supplies.
