Alternating Current Diagram. As a result the voltage level also reverses along with the current. In particular if a coil rotates in the presence of a magnetic field the induced emf varies sinusoidally with time and leads to an alternating current ac and provides a source of ac.
Alternating current is the form in which electric power is delivered to businesses and residences and it is the form of electrical energy that consumers typically use when they plug kitchen. It consists of nothing more than a source a producer of electrical energy and a load whatever is to be powered by that electrical energy. As a result the voltage level also reverses along with the current.
The phasor diagram is used.
Alternating current describes the flow of charge that changes direction periodically. Ac is used to deliver power to houses office buildings etc. This device is a special type of electrical generator. The figure to the right shows the schematic diagram of a very basic dc circuit.
