Question

in ------ Generator, field magnet are energised from an independent external source to dc current ... option a) separately excited, b) self - excited, c) shunt, d) compound​

Answer 1

Answer: Self-Excited

Explanation: Self-Excited DC Generators. Self-excited DC generators are generators whose field magnets are energized by the current supplied by themselves. In these type of machines, field coils are internally connected with the armature.

Answer 2

In the Separately excited Generator, field magnets are energized from an independent external source to dc current.

Detailed answer

As we can understand just from the name separately excited generators are excited externally.

• These are the generators in which the magnetic field is energized or excited by using an external battery or a power source that is a Dc source.
• The self-excited are energized by the inbuilt source.
• A battery can be used to energize the generator usually the batteries are pure Dc.
