General objective of this lecture is to presentation on Ohm’s Law, Coulomb’s Low, Electric Power and Generators. Ohm’s law prove that, high temperature remaining stable, the current passing through a conductor straight proportional to the potential difference or voltage across it. This means IαV. Coulomb’s Law says that, a couple of point charges attract or repel one another by a force, that is directly proportional to the product or service of the magnitude of their charges and inversely proportional towards square of distance involving them. By this two theories here is explain Electric Power and Generators.
