Definitions for "Electric Circuit"
Path followed by electrons from a power source (generator or battery) through an external line (including devices that use the electricity) and returning through another line to the source.
The complete path of an electric current including usually the source of the electric energy.
An electric circuit consisting of a power source, connecting wires or conductors, and a device that uses the electrical energy. The device that uses the energy is called the load. For current to flow in an electric circuit, there must be a complete path from the negative terminal of the power source, through the connecting wires and load, back to the positive terminal of the source. If a complete path does not exist, no current will flow, and the circuit is called an open circuit.
Keywords:  pathway, conducting, complete
