Question

principle of the DC electric generator . and I will hit brainlist button​

Answer 1

The principle of DC electric generator is electromagnetic induction.

Answer 2

Before we can explain the working principle of a DC generator, we need to cover the basics of generators.

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.
