Series parallel

  1. 1. Circuits<br />Series vs Parallel<br />
  2. 2. Spot the differences<br />
  3. 3. Series Circuit<br />A series circuit is one that connects an electrical source with its components one after another, forming one single loop. <br />
  4. 4. Series Circuit<br />There is only one path for the current to flow through. <br />The current flows through the first bulb, then through the next bulb, to light up all the bulbs.<br />
  5. 5. Disadvantage of a series circuit<br />If one of the bulbs is taken out or damaged, the other bulb will not light up.<br />Why not?<br /><ul><li>Open circuit
  6. 6. Electricity cannot pass through the circuit. </li></li></ul><li>
  7. 7. Parallel circuit <br />A parallel circuit is one that splits into two or more branches.<br />
  8. 8. Parallel circuit <br />There is more than one path for the current to flow through. <br />Some current passes through one bulb and the rest flows through the other bulb. <br />
  9. 9. Advantage of Parallel circuits<br />If one of the bulbs is taken out or damaged, the other bulb will still light up.<br />Why?<br />- One part of the circuit is still closed.<br />
  10. 10.
  11. 11. Arrangement of circuits<br />
  12. 12. Lighting at home<br />What kind of circuit is more commonly used?<br />Vote:<br />Series circuit – Raise left hand<br />Parallel circuit – Raise right hand<br />
  13. 13. Why use parallel circuit in the household lighting?<br />If one bulb is damaged or switched off, the other bulb can still work.<br />
  14. 14. How about your classroom lighting?<br />Parallel circuits<br />
