[QUOTE="hikarusteinitz, post: 5649842, member: 605065"] Thanks for the reply. I haven't bought anything yet. I wanted to read and ask about it first. What if I used a 9V battery and a copper wire then use a potentiometer to regulate the current to 4A. Will the copper wire heat up? I'm asking this just to satisfy my curiosity, so let's neglect the possibility of the copper wire breaking for a wile. [/QUOTE]
