Which of the following describes the function of an electrical fixture?

The function of an electrical fixture is to house electrical components like bulbs. Fixtures serve as the physical support and protection for light bulbs and other devices, allowing them to be safely and securely installed within a space. They provide a means to connect lighting or electrical devices to a power source while ensuring that wiring and connections are properly contained and organized. By serving this purpose, fixtures enhance the safety and functionality of electrical systems in buildings.

Other options, such as providing control over electrical flow and converting AC to DC current, describe functions that pertain more closely to other electrical components like switches or transformers, rather than the primary role of an electrical fixture. Hiding electrical connections is a secondary benefit of fixtures but does not encompass their main function, which is focused on housing the electrical components themselves.
