Answers
Explanation:
Ans:1
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.
Ans:2
An open circuit is a circuit where the path has been interrupted or "opened" at some point so that current will not flow. An open circuit is also called an incomplete circuit. ... An intentionally open circuit would be the circuit to the lights in the room that are turned off.
Ans:3
A switch is a device in a computer network that connects other devices together. ... An Ethernet switch operates at the data link layer (layer 2) of the OSI model to create a separate collision domain for each switch port.
