Question

What is the symbol of switch in ‘OFF’ position?
A.

B.

C.

D.

Answer 1

Hint: If the switch is in off position, it means that the circuit is not complete which implies that no current is flowing through the circuit. For the current to flow in the circuit, the path of current should be continuous without any breakage. If the current flows in the circuit then we can say that the switch is in on position.

Complete step-by-step answer:
To find the correct option, let us discuss all the given options and find out what each of them mean on the basis of the given symbols.
Option $A$ is the symbol for a battery. A battery is used to convert chemical energy into electrical energy.
Option $B$ is the symbol for switch in ‘OFF’ position because it represents that the circuit is not complete. A switch is used to stop the flow of current in the circuit when we don’t wish to use them
Option $C$ is the symbol of a connecting wire that is used in the circuit to join any two components.
Option $D$ is the symbol for the switch in ‘ON’ position because it represents that the circuit is complete.

So, the correct answer is “Option B”.

Note:A switch is used to disconnect the circuit when we don’t want to use them, also they are used to again complete the circuit and bring it back to work. It is a very important part of the circuit without which we will never be able to stop the circuit from working. A switch has two positions which are ‘ON’ and ‘OFF’.
