explain in brief the dc generator with diagram
Answers
Answer:
There are two types of generators – DC generators and AC generators. Both DC and AC generators convert mechanical power to electrical power. A DC generator produces direct power, while an AC generator produces alternating power.
Both of these generators produce electrical power based on the principle of Faraday’s law of electromagnetic induction. This law states that when a conductor moves in a magnetic field it cuts magnetic lines of force, which induces an electromagnetic force (EMF) in the conductor. The magnitude of this induced EMF depends upon the rate of change of flux (magnetic line force) linkage with the conductor. This EMF will cause a current to flow if the conductor circuit is closed.
Hence the most basic two essential parts of a generator are:
The magnetic field
Conductors which move inside that magnetic field.
Now that we understand the basics, we can discuss the working principle of a DC generator. You may also find it useful to learn about the types of DC generators..
