Which type of circuit allows current to follow multiple paths?

A parallel circuit allows current to follow multiple paths. In this type of circuit, there are two or more paths for current to flow. If one path becomes obstructed or fails, the current can still flow through the other paths, ensuring that the entire circuit does not stop functioning. This feature makes parallel circuits particularly useful for applications where reliability is critical, as individual components can fail without affecting the overall system.

In contrast, a series circuit has only one path for current to travel. If any component in this circuit fails or is removed, the entire circuit is interrupted. Closed circuits are simply circuits that allow current to flow because they are complete loops, while open circuits are those with breaks in the loop that prevent current from flowing. Thus, the ability of a parallel circuit to distribute current across multiple paths is what distinguishes it and makes it the correct choice in this context.
