In a basic lighting circuit, the primary components include light fixtures, switches, circuit breakers, and wiring.

Light fixtures are essential because they house the light bulbs and are directly responsible for providing illumination. Switches allow users to control the flow of electricity to the light fixtures, enabling them to turn lights on and off. Circuit breakers serve as a protective device that interrupts the electrical flow in case of an overload or fault in the circuit, safeguarding both the wiring and appliances from potential damage. Wiring is necessary to connect all the components together, facilitating the movement of electrical current throughout the circuit.

The presence of these components ensures that a basic lighting circuit can function effectively, providing a safe and convenient means to control lighting in an environment. In contrast, the other options include components that are either not specific to lighting circuits or pertain to different electrical applications entirely.
