Alternating Current and AC generator
Alternating current and direct current are the two ways that electric current can flow. The direction in which the electrons flow is the primary distinction between AC and DC. What is alternating current? An alternating current is one whose magnitude changes continuously with time and whose direction reverses periodically. In alternating current, the electrons don't move in only one direction. Instead they transfer from atom to atom in one direction for a while and then turn around and transfer from atom to atom in the opposite direction. An AC generator is used to make the flow of electrons first in one direction and then in opposite direction. What is AC Generator ? An AC generator is a device which converts mechanical energy to electrical energy. It works based on electromagnetic induction which states that whenever magnetic flux linked with the conductor changes, an emf is induced in the coil. Working Principle of AC generator. When the armature coil rotates within...
