I was doing some thinking today in math class about my project of creating a plasma arc using an ignition coil, and I figured if I had two, one operating on the negative side of ground and one on the positive side, I could double the voltage difference.
My question is, what are the voltages of the terminals pf a battery with respect to ground (like the screw on an outlet plate)?
For example, a car battery, is there a -6 volt charge on the negative terminal, and a +6 volt charge on the positive terminal, or is there a +12 volt charge on the positive terminal and no voltage difference between the negative terminal and ground?
I was wondering the same thing about wall-warts.
And ultimately, if a circuit had +12V and ground, would it work the same if the +12V was replaced with ground and the ground with -12V?
(I'll post a schematic sometime soon, until then its a 555, a PNP, an NPN, and an N-channel MOSFET)
This is probably a fairly simple question, Ive just been seeing - and ground used interchangeably and was slightly confused.
Thanks
