Question

Choose the incorrect statement.

• A. A switch is the source of electric current in a circuit.
• B. A switch helps to complete or break the circuit.
• C. A switch helps us to use electricity as per our requirement.
• D. When the switch is open there is an air gap between its terminals

Answer 1

The correct option is A

A switch is the source of electric current in a circuit.

The explanation for the correct option:

In the case of option $\mathrm{A}$

1. When a circuit is turned on by using a switch, the switch only passes the electricity into the circuit by completing the circuit.
2. Hence option $\mathrm{A}$ is correct.

The explanation for the incorrect option:

In the case of option $\mathrm{B}$

1. The transfer of electricity completes or breaks the circuit, that's accurate as it breaks the circuit even inside the "OFF" position. The transfer aids with inside the crowning glory or interruption of the circuit, that's accurate as it completes the circuit while inside the "ON" position.
2. Hence option $\mathrm{B}$ is incorrect.

In the case of option $\mathrm{C}$

1. A switch is not responsible for changing the current for our requirement.
2. Hence option $\mathrm{C}$ is incorrect.

In the case of option $\mathrm{D}$

1. When the switch is open, current does not flow through it and the circuit itself is not completed hence there is an air gap when the switch is open.
2. Hence option $\mathrm{D}$ is incorrect.

Therefore, option $\mathrm{A}$ is the correct choice.
