Current Flow

There are opposing theories yes, but I assure you DC only flows in one direction. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Its not either, its one or the other. And the situation does not affect that in any way. Unless the situation is we are using AC, not DC. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The question may be to vague, sorry. The intention was to see who knows which origin current begins at, the positive or the negative. Maybe that will simplify the answer.

Current flows from high potential to low potential which is not necessarily positive and not necessarily negative. In a DC application, the current will flow in one direction. In an AC application, the current will change with respect to the voltage.

(-) to (+) = DC.

It's a matter of opinion but the truth is found in the Electron outwards.

DC flows negitive to positive.

electrons move from the (-) to the (+), but current flows from (+) to (-).

Electric current is the flow of electric charge. The electric charge may be either electrons or ions. Ions can be positive. A flow of positive charge gives the same electric current as an opposite flow of negative charge. So yes, current can flow either + to - or - to +. Referring to car audio and how it's hooked up, electrons flow - to +.

Because the electron carries negative charge, the electron motion in a metal is in the direction opposite to that of conventional (or electric) current. While it would make more sense to draw current arrows in the direction of what is actually flowing, convention dictates that this not be the case.

Current flows negative to positive in this circumstances that the question was intended. No crazy explanations needed, you can look it up. Enough said.

- to +

Not with DC.

Yeah, yeah, he wasn't specific //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

It was out of ignorance .......

Well there you go. I read about it a while back and I just forgot.

When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor. The moment contact is made, the free electrons of the conductor are forced to drift toward the positive terminal under the influence of this field. The free electrons are therefore the current carrier in a typical solid conductor. For an electric current of 1 ampere, 1 coulomb of electric charge (which consists of about 6.242 × 1018 electrons) drifts every second through any plane through which the conductor passes.
