What type of circuit uses two or more paths for electricity to flow?

A parallel circuit is characterized by having two or more paths for electricity to flow. In this configuration, components are connected alongside each other, which allows current to divide and flow through multiple branches simultaneously. This design enhances reliable operation; if one path is broken or a component fails, electricity can continue to flow through the other paths, maintaining functionality. Each branch operates independently and can accommodate different loads without affecting the current flow in the others, resulting in uniform voltage across all components.

In contrast, a series circuit connects components end-to-end in a single path. Here, if one component fails, the entire circuit is interrupted, stopping the flow of electricity. A single-phase circuit, while it works on alternating current (AC), does not inherently specify the number of paths available for electrical flow—it can be designed as either series or parallel. A short circuit refers to an unintended low-resistance connection that diverts current flow, which can cause overheating or damage. Thus, focusing on the fundamental definition of a parallel circuit clarifies why it is the correct choice regarding multiple paths for electricity flow.
