Alternating Current vs Direct Current. Electricity flows in two ways: either in an alternating current (AC) or in a direct current (DC).

Alternating Current vs Direct Current

Electricity or 'current' is nothing more than moving electrons along a conductor, like a wire, that have been harnessed for energy. Therefore, the difference between AC and DC has to do with the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or "forward. " In AC, electrons keep switching directions, sometimes going "forward" and then going "backward. " Alternating and Direct current. Origins of AC and DC current A magnetic field near a wire causes electrons to flow in a single direction along the wire, because they are repelled by the negative side of a magnet and attracted toward the positive side. AC generators gradually replaced Edison's DC battery system because AC is safer to transfer over the longer city distances and can provide more power.

Created by The Omega Point Project. The paradox of our time in history is that we have taller buildings but shorter tempers; wider freeways, but narrower viewpoints. We spend more, but have less; we buy more, but enjoy less. We have bigger houses and smaller families; more conveniences, but less time. We have more degrees but less sense; more knowledge, but less judgment; more experts, yet more problems; more medicine, but less wellness.
