The device is called a switch.
.. The device used to open and close an electric circuit is a switch.
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
When a plug key is open , the circuit is incomplete and is call open circuit.. To be continued..
An open circuit.
it is called a circuit and when it is closed is called a closed circuit and when open circuit it is called an open circuit
A switch, circuit breaker, fuse, or switching transistor can do that.
A switch is a device that is used to open and close an electrical circuit that is is connected into.

A switch.
A basic manual operating switch is able to open or close a circuit. There are electronic components that will also control the working of a circuit.
That function was traditionally implemented in the form of a mechanical deviceknown as a "switch".The practice became so firmly embedded in the art and science of electricitythat the word became the generic term for any device that could performany similar function, so that now we have "switching transistors", integrated"CMOS switches", and even central office telephone-circuit "switches".
The electric path which starts from the positive terminal of a cell or battery ends at its negative terminal, without any break, is called closed electric circuit or complete electric circuit. The electric path,which starts from the positive terminal of a cell or battery, is broken at some point, is called open electric circuit or incomplete electric circuit.
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
A light switch
A switch is normally used to open or close an electric circuit, but it can also be used to change the flow from one circuit to another.
A device that opens and closes a circuit is called a switch.
which electric element should be used so as to open the closed electric circuit
