What do ohms say about my plating process?
On a rectifier that I use for a copper cyanide bath, I have two gages, one tells me the amps, and the other one volts. Is there an established Ohm value I should be aiming for?

Hi, Juan.
Ohm's law says that the resistance (ohms) equals the voltage divided by the amperage. Only two of the three values can be independently varied. The third is the result of the other two. If your bus bars are adequate size, and the connections are clean, and the plating solution is properly made up and operating at the correct temperature, the only way you can change the ohms is by moving the work closer to the anodes or further away.
