120v or 240v better for mining? I mean country frequency, leaving a country like US that use 120v 60hz to another country that use 240v 50hz doesn't this impact mining in any ways?
Remember the school physics course and the well-known formula:
P=U*I
P- Constant value
If we decrease the electrical voltage(U), then we increase the strength of the current(I).
And the higher the current, the thicker the wires are needed for the design of the electrics.
https://en.wiktionary.org/wiki/kilowatt-hourIn Russia, energy consumption is recorded in kilowatt*hour
If a farm consumes 1 kilowatt and works for 1 day, then its consumption will be equal to 24 kilowatt*hour
For industrial facilities with high energy consumption, it is better to use 240 volts.
