Current and voltage ratings in dc plugs and wires? Answered
I had this great idea to turn old cell phone chargers into DC extension cords. Cell phone wires are nice because of their curly spring wires. I worried the wire gauge might not be large enough to handle my project. Here is my question. On websites that list current ratings for standard wire gauges, they list current limits but not voltage limits. Why is this? If a 22 gauge wire can handle .92 amps does it really not make a difference whether it is 1 volts or a million volts? Why don't they use watts to list how much power a wire can handle. Watts take both volts and amps into account.
Another mystery is that my DC plugs are rated for 6-10 volts. Why are the plugs rated for volts but not amps? What would happen if I used these plugs for 4 volts, which I plan to do.
