Which component provides external electrical power to the system?

Which component provides external electrical power to the system?

• A. External Power Connector
• B. Battery 24 Volt
• C. Alternator
• D. Transit Light Assemblies

Answer: (A)

The key idea is identifying the part that brings power in from outside the system. The external power connector serves as the interface to an outside power source, such as a ground power unit or utility supply, delivering electrical power into the system. The other options are internal or dependent sources: a 24-volt battery stores and provides power from within the system, the alternator generates power on-board while the system is running, and transit light assemblies are loads that consume power rather than supply it. So the external power connector is the component designed to supply external electrical power to the system.
