Equipments like electric bulbs make use of the heating effect of the electric current. Electrical conductors having higher resistivity are used here. Hence, Tungsten metal is used to make a solenoid type, coil in an electric bulb as it has high resistance and high melting point. The light bulb glows when high current is passed through it. Due to the current, this wire gets heated (to nearly 34000C) and emits light. The hot wire also radiates heat to a certain extent.
