i was creating hydrogen using the way with electrolysis and i thought that the higher the volts the faster it would turn the water to h2 o i first used 2 aa batterys and it made alot of very small bubbles then i found a ac to 12v dc wall converter. i put the positive and negative in the water but it didnt bubble much more than the aa's did. maybe the converter was daulty.
but is the process supposed to be faster when you use higher voltage?

Hmm i have 2 think about this

I don't know about changing water to gas but i do know that when you electroplate circuit boards it the amps that make it plate faster not the volts

it probly wudnt. it wud just steam imo

Hook the wires to two metal plates, then put the two metal plates as close as possible without them touching. That should speed things up a bit
