Lesson in Electrochemistry....
We know that:
1 liter = (approximately) 1 quart.
1 amp of electricity 376 x 10^18 electrons per minute
1 mole of a gas = 22.4 liters
1 mole of a gas = 6.02 x 10^23 molecules (Avogadro’s number).
Start with 2 molecules of water then change to moles
H2O + H2O + 2 electrons = H2 + H2 + O2
or 1 mole + 1 mole + 2 electrons = 1 mole + 1 mole + 1mole
or 22.4 L + 22.4 L + electrons = 22.4L + 22.4 L + 22.4 L
If we assume the above all takes place in one minute then the number of amps required to change 2 moles of water ( 36 grams) to HHO gas is equal
to 12.02 x 10^23 / 376 x 10^18 = 3,190 amps.
But this current produces 67 liters of gas in one minute so the amount of electricity to produce 1 liter of gas per minute is .. 3,190 / 67 = 47 amps.
