Which statement best describes a generator's function?

• A. It Stores Electrical Energy In Chemical Form
• B. It Converts Mechanical Energy Into Electrical Energy Using Rotating Motion And Magnetic Fields
• C. It Dissipates Energy As Heat
• D. It Uses A Fixed Source Of DC With No Magnetic Field

Answer: (B)

A generator works by turning mechanical energy into electrical energy through rotation in a magnetic field. When the rotor spins, the magnetic flux linking the conductors changes, inducing a voltage in the windings. This electromagnetic induction requires both motion and a magnetic field, which is why turning parts inside a generator generates electricity.

Storing energy chemically is what a battery does, not a generator. Dissipating energy as heat describes a resistor or braking load, not energy creation. Relying on a fixed DC source with no magnetic field would not produce new electrical energy, since induction requires motion and magnetism.
