Explanation:
Light bulbs glows when electricity is passed through the filament. High melting point tungsten has melting point of 3422C so it doesn't melt when current is passed it doesn't melt.This helps the filament not to get separated from the electrodes. Due to all these properties of tungsten, it is used in light bulbs.
