Can you connect a copper cable to a battery without protection?
Hello folks,
I wanted to ask if you can connect a copper cable to a battery without protection, for example, to split water into oxygen and hydrogen. To explain it even better: A 9-volt battery connected to a copper cable. This copper cable is also connected to an electrically conductive object, which is supposed to split the water. Would that work, or do you need, for example, alligator clips with a cable to connect a battery to an object?

Since in a normal 9V block you can easily grasp the poles, there is not much to do with the cables (except short circuit)

The electrical current does not at all shy about the type of stable conductive connection. It doesn’t matter if you guide it through a solder joint, a blazer clamp, a crocodile clamp, an iron curtain rod, an automobile fender or a gutter.
For a visible electrolysis with ascending bubbles or even with an arc, however, a flashlight battery should be far too weak.
Yeah, I can. You can just connect the cables as long as you don’t run a short circuit. It doesn’t even have to be copper cables. Basically, every kind of metal works. e.g. a paper clip or aluminum foil.
Only with the electrodes in the water is it important that they are made of a suitable material. Graphite is very good. You can simply use pencils.

A short circuit would only stand if I were to connect minus and plus pole with the copper cable or not?
Right. Let it be.
Or when the two cables touch and they are not insulated.
How do you want the cables (you need two)
connect to the battery
So the two cables wind and connect to the battery (Plus and minus) and the two objects
You want to wrap the cables around the contacts?
Yes
