Question

A device that is used to break an electric circuit is called a ___________.

Answer 1

1. An electric circuit is a closed and continuous path through which electric current flows.
2. An electric circuit essentially consists of a switch or key that helps to break or create the continuous path through which electric current flows.
3. When the switch is “on”, electric current flows through the circuit.
4. When the switch is “off”, no electric current flows through the circuit.
5. Below is the diagram showing a circuit in which the bulb glows only when the switch is “on”.

Hence, a device that is used to break an electric circuit is called a switch.
