[QUOTE="mcatrophy, post: 1149759, member: 3187"] [off topic background information] It is a normal convention to say that electricity flows from positive to negative. This was the best guess prior to the discovery of the electron, and it is most unlikely that this convention will change in the forseeable future. In any normal conductor, electrons are the majority carrier of electrical energy. In some materials, notably semiconductors, it is possible for the energy to flow in the form of "holes", where in physical terms a "hole" is the absence of an electron. Here there will be a positive charge on an atom that is missing an electron. As the current flows, the hole will be filled by an electron from the adjacent atom, so the positive charge leaves the first atom and transfers to the next. This continues along the material, so constituting a positive current flow. The computing device you are using to read this relies on this mechanism. [/off topic] [/QUOTE]
