... Why is this !! Is God just screwing with me ?
Bear in mind that this is defined in terms of Conventional current, which defines current as flowing from Positive to Negative. This is, of course, reverse to Electron flow, in which the current is observed as electrons migrating from negatively charged areas (excess electrons) to positively charged areas (shortage of electrons). Conventional Current definition was in common use before electrons were known.
Some times it doesn't pay to think too much. Just as the occupant of the top bunk must climb up to lie down, and climb down to get up, it's often best to just nod, smile, and carry on! [/font]
