Power supply for nickel electroplating

I m going to do nickel electroplating with current of 20 Ampere, however, I know nothing about the power required to use and would like to know what voltage require to produce the constant 20 ampere in my experiment. It is because I need to calculate its power cost. Thanks to anyone who answer my question.

The biggest factor determining the required voltage is the distance from the anode to the cathode. Some high production nickel plating is done at 5 volts so I doubt you need more than that. Good luck.

If you are already plating at 20 amps simply put a voltmeter across the cell.
However, the power consumption is not the output at the tank, it is the current at mains voltage used by the rectifier. If there is no work in the tank and the rectifier is switched on, It will still be drawing current and costing money. How much depends on the efficiency of the rectifier.
The best way to find the running cost is to speak to an electrician about borrowing a power meter.
One simple solution is to read the main supply power meter with the rectifier on and off. The cost is the difference.
