How does insulation help electrical safety?

• A. It prevents contact with live conductors and reduces heat loss.
• B. It increases current flow through the conductor.
• C. It converts electrical energy into sound.
• D. It changes the circuit's voltage.

Answer: (C)

Insulation around electrical conductors provides a non-conductive barrier that keeps electricity from escaping to anything you might touch. This protects people from electric shocks and helps keep the current confined to the intended path, reducing the risk of short circuits and fires. It doesn’t make current flow more, it doesn’t turn electrical energy into sound, and it doesn’t change the circuit’s voltage.
