उत्तर
Tungsten is used to make a solenoid-type coil in an electric bulb.
Explanation:
The electric bulb works on the principle of the heating effect of electric current. The solenoid-type coil of the bulb has high resistivity and a very high melting point. When current is passed through the bulb, the solenoid-type coil of the bulb gets heated to a high temperature (up to 3400°C) and starts glowing.
