Hi, I am experimenting with hydrogen fuel and I am wanting to boost 12 vdc so I can produce as much hydrogen as I can. On another thought I am hoping someone could tell me what kind of voltage is at the magnetron in a micro wave oven. I have a few micro waves lying around and was thinking what could I do with them, parts wise. I wanted to try high freq. voltage dc if any way possible. Any way I would appreciate any in put. Thanks John.

DC doesn't have a frequency.

Electrolysis speed is a combination of both voltage and current, so 12V at 30 Amps would produce more hydrogen and oxygen than 100V @ 1mA

Technically, DC is a single polarity, but not necessarily constant. So a DC waveform can have frequencies, just like an AC waveform.

Hydrogen, and the voltages in microwave ovens, are both extremely dangerous. Please be extremely careful!

You may be confused by the DC and AC coupling options on oscilloscopes. These aren't the same as DC and AC voltage reading. DC voltage has always a single value and stable polarity. Any fluctuating voltage is considered AC and is made up from various frequency components (see Fourier analysis) and possibly from a DC component (average value).

Chemical action is proportional to the current ( voltage matters mostly as it drives the current ). Early definitions of charge ( and thru that current ) were based on chemical definitions.
