• A. We should never touch a lighted electric bulb connected to the mains.
• B. We should never experiment with the electric supply from the mains or a generator or an inverter.
• C. We should never use just any wire or strip of metal in place of a fuse.
• D. We should never turn the switch in ON position.

Answer 1

The correct option is D

We should never turn the switch in ON position.

Electric switch:

1. A basic manual electromechanical unit is the most common type of electric power switch.
2. When a switch is in the ON position, it completes the circuit and allows the current to flow through.
3. Similarly, a switch is in the OFF position when it breaks the circuit and prevents current from passing through.

Hence, Option(D) is correct.
