Open and Closed Circuit: a 3D model for Class 6–8 Science, covering A bulb lights only when there is a complete, closed conducting path from the + terminal of the cell back to the -…, A switch opens or closes the circuit: an open switch leaves an air gap that breaks the path., The bulb is part of the loop: the path goes in at one terminal, through the filament, and out at the other., Metals are conductors and complete a circuit; plastic is an insulator and leaves it open., Conventional current is shown flowing from + to - in the outside circuit; the arrows are a convention, not electrons..

  • A bulb lights only when there is a complete, closed conducting path from the + terminal of the cell back to the -…
  • A switch opens or closes the circuit: an open switch leaves an air gap that breaks the path.
  • The bulb is part of the loop: the path goes in at one terminal, through the filament, and out at the other.
  • Metals are conductors and complete a circuit; plastic is an insulator and leaves it open.
  • Conventional current is shown flowing from + to - in the outside circuit; the arrows are a convention, not electrons.
  • Current starts everywhere in the loop at once when the circuit is closed, so the bulb lights straight away…
