Answer:
The solenoid type coil of bulb has high resistivity and very high melting point. When current is passed through the bulb, solenoid type coil of bulb gets heated to high temperature (upto 3400 °C) and starts glowing. Hence, tungsten metal is used to make a solenoid type coil in an electric bulb.
