Explain AC Generator or Alternator in Three Phase
AC generator (Alternator) – Three phase A single-phase a.c. generator or alternator has only one armature winding. If a number of armature windings are used…
What is Eddy Current?
Foucault in the year 1895 observed that when a mass of metal moves in a magnetic field or when the magnetic field through a stationary…
Describe Working Process Eddy Currents
Working process Eddy currents Eddy currents are currents induced in conductors to oppose the change in flux that generated them. When a conductor in the…
Explain Methods of Producing Induced emf
Electromotive force (EMF) is the characteristic of any energy source capable of driving electric charge around a circuit. It is abbreviated E in the international…
How Emf Induced by Changing the Magnetic Induction?
Emf induced by changing the magnetic induction The magnetic induction can be changed by moving a magnet either towards or away from a coil and…
Explain how Emf Induced by Changing the Area Enclosed by the Coil
Minimum things required to induce emf are conductor, flux, and movement of the conductor in the magnetic field. EMF induced by changing the area enclosed…
How Emf Induced by Changing the Orientation of the Coil?
Emf Induced by Changing the Orientation of the Coil The magnetic induction can be changed by moving a magnet either towards or away from a…
Principle of AC Generator (Dynamo) Single Phase
The ac generator is a device used for converting mechanical energy into electrical energy. The generator was originally designed by a Yugoslav scientist Nikola Tesla.…
