Question

A. Dc generators comes under self excitation is
A. Series generator
B. Shunt generator
C. Compound generator
D. All of the above​

Answer 1

Answer:

DC generators are classified based on how their fields are excited (i.e. produced). There are three methods of excitation, and thus three main types of DC generators:

Permanent Magnet DC Generators – Field coils excited by permanent magnets

Separately Excited DC Generators – Field coils excited by some external source

Self Excited DC Generators – Field coils excited by the generator itself

Self-excited DC generators can further be classified depending on the position of their field coils. The three types of self-excited DC generators are:

Series Wound Generators

Shunt Wound Generators

Compound Wound Generators

A portable generator is an example of a practical application that utilises such technologies.
