Final answer:
A closed circuit is the path of an electric current from the generating source back to its original source. It includes the generator or power source, conducting wires, and any components or devices connected to it.
Step-by-step explanation:
The path of an electric current from the generating source back to its original source is called a closed circuit. A closed circuit is a complete loop or pathway through which electric charges can flow. It includes the generator or power source, conducting wires, and any components or devices connected to it.
For example, in a simple electric circuit, such as the one shown in Figure 20.3 (a), the closed path for current flow is provided by the conducting wires that connect a load to the terminals of a battery. The load can be a light bulb, resistor, or any other electrical component that uses the electricity.
In order for the current to flow continuously in a closed circuit, there must be no breaks or gaps in the pathway, and there must be a complete circuit from the generator back to its original source.
