Electrolysis question

[Moe (fl)]

I am a newbie to electrolysis. I built an electrolysis device with a 12V .33A cellphone charger and have used it a few times with mix results.

Is there an easy way to tell the positive from negative wires (besides looking for bubbles)? Do they sell a meter that will tell me this?

I have noticed that after 20 minutes the charger gets really hot. Do I need to use a better/bigger charger or is this common to all chargers?

Thanks for the replies.

I'm pretty new too....but for what its worth.... look at the wires closely, the wire that is grooved bumpy should be the neg - (at least on the 4 chargers I have they are neg)

Another thing You can try. Take a non value clad penny if polarity is wrong, it will oxidise the penny real fast.

A basic ohm meter will show you positive and negative.
As for the charger getting hot. All 3 of mine (200, 600, & 1250ma) get hot pretty quickly.
On iron objects, I leave them on for 12 hours without any problems, but, just for safety,
I leave them on outside. Can't be too careful.

Thank you Tymcmurray and Haboo!

This will help me a lot.

Happy Hunting!
