Question

When a switch is in OFF position,

1. circuit starting from the positive terminal of the cell stops at the switch.
2. circuit is open.
3. no current flows through it.
4. current flows after some time. 

Choose the combination of correct answer from the following.

Options

• all are correct

• (ii) and (iii) are correct

• only (iv) is correct

• only (i) and (ii) are correct

Answer 1

(ii) and (iii) are correct

Explanation:

• When a switch is in the OFF position:

  • The circuit is open (meaning there is a break in the circuit).

  • No current flows through it because an open circuit prevents the flow of electricity.

The other options are not correct because:

• Option (i) (“circuit starting from the positive terminal of the cell stops at the switch”) is not a complete statement. It doesn’t fully explain the condition of the circuit when the switch is OFF.

• Option (iv) (“current flows after some time”) is incorrect because no current flows when the switch is OFF.

So, the correct combination is (ii) and (iii).
