direct current. This type of generator is called D.C. generator. Similarly, instead of a half ring, if a full ring is used then, A.C. current can be generated and such a generator is called an A.C. generator.
Electric Generator. ... and working of an electric generator (AC). Draw a neat diagram and label it. ...
(a) Draw a labelled diagram of an electric generator. Explain its construction and working in brief. (b) Write down any two characteristics of magnetic field lines of a bar magnet.
The law of physics that governs the creation of electric current within an AC generator is called Faraday's law. The value of the voltage produced by an AC generator generally depends on three different factors: the number of turns in the coil, the strength of the magnetic field within the device and the speed at which the coil or the field ...
When electric current is passed into the rectangular coil, this current produces a magnetic field around the coil. The magnetic field of horse shoe-type magnet then interacts with the magnetic field of the coil and causes the coil to rotate continuously.
It worked on the principle of Electromagnetic Induction. When amount of flux linked with the coil changes, an e.m.f. is induced in the coil.
2) Linear electric generator- In this form, a sliding magnet moves back and forth through a solenoid – a spool of copper wire, which in turn induces an alternating current into the loops of wire. 3) Variable-speed constant-frequency generators- These generators are in use to harvest natural sources of mechanical energy (wind, tides, etc.) to ...
Principle: Electric generator works on the principle of electromagnetic induction. It converts mechanical energy into electrical energy.
The magnitude of induced emf can be calculated from the emf equation of dc generator. If the conductor is provided with a closed path, the induced current will circulate within the path. In a DC generator, field coils produce an electromagnetic field and the armature conductors are rotated into the field.
(a)Principle:It works on the principle of Faraday's law of EM induction.Whenever a coil is rotated in a uniform magnetic field about an axis perpendicular to the field a magnetic flux linked with coil changes and an induced emf is set up across its ends.The coil is horizontal and is rotated clockwise.
