Which type of circuit allows current to follow multiple paths?

A parallel circuit is characterized by its ability to allow current to follow multiple paths. In this arrangement, components are connected alongside each other, which means that each component has its own direct connection to the supply voltage. If one path in a parallel circuit fails or is broken, the current can continue to flow through the other paths, thus maintaining the functionality of the circuit as a whole.

This structure provides several advantages, such as ensuring that devices connected in parallel receive the same voltage and allowing for independent operation of these devices. If a light bulb fails in a parallel circuit, for instance, other bulbs or devices connected to the same circuit may continue to operate normally, which is not the case in series circuits where a break in the path will interrupt the entire circuit.

In contrast, closed circuits allow current to flow but do not specifically create multiple paths. Series circuits, on the other hand, require components to be connected in a single path, meaning if one fails, the entire circuit is interrupted. Open circuits are incomplete paths that do not allow current to flow at all. Thus, the definition and functionality of a parallel circuit make it the correct choice for this question.
