What supply current in generator?
A direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. The basic principles of operation are the same as those for synchronous generators.
How does a AC generator produce electricity?
Simply, a generator uses the rotation of a coil of wire in a magnetic field to produce electricity. (The principle of electromagnetic induction/ faraday’s law : Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be “induced” in the coil. )
How does direct current generator work?
The working principle of the DC generator is based on Faraday’s laws of electromagnetic induction. When a conductor is located in an unstable magnetic field, an electromotive force gets induced within the conductor. The induced e.m.f magnitude can be measured from the equation of the electromotive force of a generator.
What are the two parts of generator?
In general form, a synchronous generator is having two parts. That is rotor and stator the rotor part consists of field poles and the stator part consists of armature conductors. Supplying electrical energy is the main source of synchronous generators.
What are the parts of a generator answer?
The key parts of DC generators are yoke, poles, pole shoes, armature core, armature winding, commutator, brushes, magnetic field system, commutator, end housings, bearings, and Shafts.
How do you produce current?
To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.
How DC current is produced?
Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators. Direct current was supplanted by alternating current (AC) for common commercial power in the late 1880s because it was then uneconomical to transform it to the high voltages needed for long-distance transmission.
