• multiple terminals and single filament

• single terminal and single filament

Filament of a bulb is made up of

• Alumunium

• Iron

• Steel

• Tungsten

Why tungsten is used for making bulb filaments ?

• Because tungsten has a high melting point and can withstand high temperatures

• Because it is lightweight

• Because it is weak
