Circuit

A device, or system of devices, that allows electrical current to flow through it and allows voltage to occur across positive and negative terminals.

The complete path of an electric current, including the generating apparatus or other source; or, a specific segment or section of the complete path.

The complete path between two terminals over which one-way or two-way communications may be provided. 2. An electronic path between two or more points, capable of providing a number of channels. 3. A number of conductors connected together for the purpose of carrying an electrical current. 4. An electronic closed-loop path among two or more points used for signal transfer. 5. A number of electrical components, such as resistors, inductances, capacitors, transistors, and power sources connected together in one or more closed loops. 6. A fully operative communications path established in the normal circuit layout and currently used for message, WATS access, TWX, or private line services. [47 CFR Pt.36-A]
