Q

Which of the listed devices is an electrical device which employs a stationary armature and a rotating electromagnetic field that is commonly used aboard ship?

🔍 Key Concepts

• Differences between AC (alternating current) and DC (direct current) machines • What an alternator does compared to a generator • Meaning of stationary armature and rotating magnetic field in marine electrical systems

💭 Think About

• Which of these devices is specifically designed to produce electrical power for the ship’s main distribution system? • Which options are mainly control/regulation devices rather than primary power-producing machines? • In a typical shipboard AC power plant, what part actually turns and what part stays still?

✅ Before You Answer

• Identify which choice is the main AC power source for most modern ships • Eliminate any options that are primarily control or regulation components, not prime power producers • Match the device whose normal construction uses a stationary armature (stator) and a rotating electromagnetic field (rotor)
