Final answer:
The ground completes an electric circuit and carries the current safely away, while conductors such as metal wires provide a path for current flow. Fuses and circuit breakers provide overcurrent protection.
Step-by-step explanation:
The component that completes an electric circuit and carries the current safely away is known as the ground. In an electric circuit, a complete path must be established for electric charges to flow.
This is typically provided by conductors, usually metal wires, which connect a power source to a load like a light bulb or resistor. For safety and to prevent potential overcurrent, devices such as fuses and circuit breakers are used. They protect the circuit by breaking the flow of electricity when the current exceeds safe levels.
For instance, a fuse contains a thin wire that melts when too much current passes through, thereby interrupting the circuit and preventing damage or fire.
The component that completes an electric circuit and carries the current safely away is called a conductor.
A conductor is a material that allows electric charge to flow through it. Common examples of conductors are metals like copper and aluminum. When an electric circuit is complete, the conductor provides a pathway for the current to flow, allowing it to safely reach its destination.
Other examples of conductors include water, which conducts electric current in a water circuit, and the wires in an electrical device, which conduct the current from the power source to the different components.
