Correct Answer - Option 3 : Closed, ON

Concept:

Circuit

  • A circuit is the path of electric current to flow. 
  • It consists of a source of current or potential difference that can be an electric cell or a battery. 
  • It may consist a circuit breaker or switch and other devices like a bulb. 


Switch

  • A switch is a device that acts as a circuit breaker as per requirement. 
  • When the switch is closed, that means the path of the current or circuit is closed or completed. 
  • We say the switch is ON in this case. 
  • When we don't want the current to flow through the connected device, the switch is made off.
  • The circuit is made to open so that no current can flow through it.


Explanation:

So, to make the current flow, we need to switch ON. This is the case when the current is flowing and the switch is closed. 

So, the correct option is Closed, ON.
