A:Answer Closed circuit means a complete electrical connection around which current flows or circulates. When you have a series of electrical wires connecting to each other and completing a circuit so that current travels from one end of the circle to the other, this is an example of a closed circuit.
An open circuit is one where the continuity has been broken by an interruption in the path for electrons to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.
