Answers
Answer:
The initial electromagnetic generator (Faraday disk) was invented by British scientist namely Michael Faraday in the year 1831. A DC generator is an electrical device used for generating electrical energy. The main function of this device is to change mechanical energy into electrical energy. There are several types of mechanical energy sources available such as hand cranks, internal combustion engines, water turbines, gas and steam turbines. Generator provides power to all the electrical power grids. The reverse function of the generator can be done by an electric motor. The main function of the motor is to convert electrical energy to mechanical. Motors, as well as generators, have similar features. This article discusses an overview of DC generators.A DC generator or direct current generator is one kind of electrical machine, and the main function of this machine is to convert mechanical energy into DC (direct current) electricity. The energy alteration process uses the principle of energetically induced electromotive force. The dc generator diagram is shown below.A DC generator is also used as a DC motor by without changing its construction. Therefore, a DC motor otherwise a DC generator can be generally called as a DC machine. The construction of a 4-pole DC generator is shown below. This generator comprises of several parts like yoke, poles & pole shoes, field winding, an armature core, armature winding, commutator & brushes. But the two essential parts of this device are stator as well as the rotor.
Answer:
DC motor in which the current is direct current ans in AC current is the alternate current
