Which of the following defines the path of an electrical circuit?

A closed circuit is defined as a complete, unbroken path through which electric current can flow. In a closed circuit, all components, such as power sources, conductors, and loads, are properly connected, allowing electricity to travel from the power source, through the load, and back to the source. This continuous loop is crucial for the operation of electrical devices.

In contrast, an open circuit does not provide a complete path for current flow because there is a break somewhere in the circuit, meaning electricity cannot flow and the devices will not operate. A short circuit occurs when electricity takes an unintended path, often bypassing the intended load, which can lead to excessive current flow and potentially hazardous situations. A ground circuit is related to safety and grounding practices to protect against electric shock but does not define the path itself in the same way that a closed circuit does.

Therefore, the definition that fits the concept of being a complete path for electrical flow is that of a closed circuit.
