Detailed Solution

The above statement is True.
An electric bulb will glow when an electric current is passed through it. While it's glowing, the electric energy is converted into heat energy. Thus, heat is formed on the surface of the bulb. When the towel is used to cover the bulb, it will start burning due to a large amount of heat on the bulb's surface.
