: The resistance and melting point of nichrome is much higher than that of copper. Due to the high resistance, a lot of heat is generated when electricity flows through the nichrome wire. Due to the nature of nichrome, the water in the electric kettle heats up very fast The filaments of all the electric bulbs we use at home are made of tungsten. Due to the high resistance and melting point of tungsten, it can easily convert electrical energy into light energy.
