Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Alternator?Automotive electrical systems and utility-scale power generation
2. What is the primary function?Conversion of mechanical energy to AC electrical energy via electromagnetic induction
3. What is the dominant design?Rotating magnetic field (rotor) within a stationary armature (stator)

Synchronous Generator: An AC electrical generator where the rotor rotates at a speed synchronized with the frequency of the generated current.
Electromagnetic Induction: The process by which a voltage is produced in a conductor when it is exposed to a changing magnetic field.
Armature: The stationary part of an alternator that contains the coils of wire where electricity is generated.
Rotor: The rotating part of an alternator, typically containing electromagnets or permanent magnets that create the magnetic field.
