Why does tungsten metal used to make solenoid type coil in an electric bulb?
Advertisements
उत्तर
Tungsten metal is used to make solenoid type coil in an electric bulb because:
- Tungsten metal has high resistance and high melting point (nearly 3422°C)
- Because of current it gets heated at high temperature and emits light.
