Fundamentals of Electrical Generators Quiz Practice…

Q: The principle of operation for all electrical generators is based on:

Faraday's Law of Electromagnetic Induction — Generators convert mechanical energy to electrical using induced EMF based on Faraday's law.

Q: In a DC generator, the commutator's primary function is to:

Convert AC voltage generated in the armature to DC voltage — The commutator reverses the current direction periodically, resulting in unidirectional (DC) output.

Q: The rotating part of a generator is called the:

Rotor — The rotor physically spins, housing the armature or field windings depending on generator type.

Q: The field winding in a generator produces:

A stationary magnetic field — The field winding generates a static magnetic field, which the rotor then interacts with to produce voltage.

Q: What is the purpose of the prime mover in a generator system?

To supply the mechanical power to rotate the generator's rotor. — The prime mover (e.g., turbine, engine) supplies mechanical energy to spin the generator's rotor.
