What type of circuit is used for normal residential lighting?

In residential lighting, parallel circuits are commonly used because they allow multiple light fixtures to operate independently. In a parallel circuit, each light has its own direct path to the power source. This means that if one light bulb burns out or is removed, the other lights will continue to function. This is a crucial feature for residential settings, where reliable lighting is needed in different areas of a home.

Additionally, parallel circuits help ensure that all fixtures receive the same voltage, which is essential for consistent illumination. This setup also offers the advantage of being able to add or remove fixtures without disrupting the entire lighting system. Therefore, the use of parallel circuits in residential lighting systems provides both functionality and convenience for homeowners, making it the preferred choice.
