∙ 8y agoIn DC circuits, the positive pole is usually marked red (+) and the negative pole is usually marked black (-), but other color schemes are sometimes used in automotive and telecommunications systems.
the larger prong is "positive" i think. it starts at a phase and switches with the other prong, it is arbitrary UNLESS it is an unshielded appliance and it makes an electrical connection with another unshielded electrical connection that is "OUT OF PHASE". the larger plug ensures appliances are in phase; however 3 prongs use a ground so that is where things get more complicated, all i have gathered so far is that the two prongs on 3 3 prong that are not the ground/lower prong can not be switched so the left and right have a designation, so applying this to two prongs, the larger prong is aligned i believe to be the same starting polarity/phase as the three prong i think.
SOMEONE WITH THE DETAILED KNOWLEDGE PLEASE EDIT THIS, THE LAST ANSWER WAS WRONG AT LEAST ABOUT THE WIRE COLORS and i think about the prong. (even if prong phase/polarity doesn't matter if unrelated to other appliances it is in reality important if learning the basics of mains power and electrical device construction.
