Detailed explanation-1: -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. The terms “open” and “closed” refer to switches as well as entire circuits. An open switch is one without continuity: current cannot flow through it.

Detailed explanation-2: -Closed Circuit: In a closed circuit, the connected source and load form a closed-loop path. We need a switch to make (ON) and break (OFF) the circuit for the electrical and electronic circuits to work (open circuit and closed circuit).

Detailed explanation-3: -There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current.

Detailed explanation-4: -A closed circuit allows an uninterrupted flow of electricity from the source of power, through the conductor or wire, to the load, and then back again to the ground or source of power.

Detailed explanation-5: -A power supply. A load. A control device. A current path. 19-Apr-2020
