Terminals in given the bulb are label 3 and label 4. A terminal is the part through which the electricity is passed to the filament of the bulb.

  • Terminals are those part through which the electricity is passed to the filament of the bulb.
  • They are made up of metal because their work is to conduct electricity to the filament.
  • Terminals are like gates, if you want to go inside the room there is only one way that is passing through the gate.
  • In case of bulb, if you want to enter the current into the filament you must pass it through the terminals. Without passing through terminals there is no other way.
