Detailed Solution

The above statement is true.
The tightly wound coils are made of nichrome wires with a high melting point and low conductivity. They offer high resistance to the current, and thus the energy changes from electrical to heat energy. Low cost of manufacturing, strength, stability at high temperatures and resistance to the flow of current are some of the properties that make nichrome an ideal choice. Electric heating elements like heat guns, hot air guns and hair dryers use nichrome wire.
