A.C generator or dynamo is a device which converts mechanical energy into electrical energy. Actually, the name generator is a misnomer because it does not generate any energy. It converts mechanical energy into electrical energy. Definition of A.C Generator   An a.c generator is the one which produces a current that alternates or changes its direction regularly after a fixed interval of time, i.e., it is a device which converts mechanical energy into alternating form of electrical energy. The present form of a.c generator is due to Nikola Tesla , The great Yugoslav scientist who built it in the year 1888 . Working principle of A.C Generator The working of an a.c generator is based on the principle of electromagnetic induction . When a closed coil is rotated in a uniform magnetic field with its axis perpendicular to the magnetic field, the magnetic flux linked with the coil changes and an induced EMF is produced and hence a current is set up in it. Components of A.C Gene
