Question

Out of the given situations, in which possible situation is there a chance for you to get an electric shock?

• A. Operating a switch with a dry hand.
• B. Using a wire with an insulation.
• C. Changing a bulb when the switch is ON.
• D. Removing a plug pin when the switch is OFF.

Answer 1

The correct option is C Changing a bulb when the switch is ON.

Changing a bulb when the switch is ON can cause electric shock because there is still a flow of current, which can harm you.
In all other situations, you are safe:
Operating a switch with a dry hand is the correct way to do so as there is no presence of water, which can easily conduct electricity to your body.
Using a wire with insulation is the correct way to do so as the insulation material hinders the flow of current to your body.
Removing a plug pin when the switch is OFF is the correct way to do so as there is no current flow happening here.
