2.9 explain why a series or parallel circuit is more appropriate for particular applications, including domestic lighting

Parallel circuits are more appropriate for domestic lighting.

  • Bulbs connected in parallel glow brighter because 2 bulbs in series have a higher tresistance than a single bulb, and current doesn’t have to flow through the combined resistance that a series circuit poses
  • If one lamp blows, the other lamps will continue to glow. This is because there is still a complete circuit
  • You are able to control each light individually in a parallel circuit
  • In a a series circuit the potential difference across each bulb is smaller, so the brightness of the bulb varies
