What do you mean by generator? How does it work and what are the parts of generator?
Generator Generator is a machine which converts mechanical energy into electrical energy. In generator there is a shaft which is placed in a magnetic field. As the shaft moves or rotate there shaft cuts the magnetic field due to which emf is produced. Basically there are two types of generator. i) Separately excited ii) Self excited As there is a magnetic field in generator and armature coil is placed in that magnetic field. When the armature is rotated by external force then due to rotation there the armature coil cuts the magnetic field and also we can say there change in magnetic field in the coil takes place. Due to change in magnetic field there the emf induced which is directly proportional to the rate of change in magnetic field. Generator works on the principle of Faraday second law or Faraday law of induction which says that ...
