What term describes a complete path through which electricity flows?

1. Open circuit

2. Closed circuit

3. Parallel circuit

4. Series circuit

The correct answer is: Closed circuit

A complete path through which electricity flows is referred to as a closed circuit. In a closed circuit, the electrical current has a continuous loop to travel through, allowing devices, such as lights or motors, to operate. This means that all components in the circuit are connected without any breaks, facilitating the flow of electricity seamlessly. In contrast, an open circuit refers to an incomplete pathway, preventing the flow of electricity, which means that devices cannot function. Parallel and series circuits describe specific configurations of closed circuits rather than defining the concept of a complete circuit itself. In a parallel circuit, multiple paths exist for electricity to flow, while in a series circuit, there is only one path. However, both types still represent variations of a closed circuit since they allow for electricity to flow continuously through the circuit's components.
