  1. Circuits, Circuits Everywhere

  2. Circuit 1 • Bulbs are dim • SERIEScircuit www.bbc.co.uk

  3. Circuit 2 • There are different “branches” of the circuit • Each bulb is connected to the battery by a separate path • Bulbs are bright • Parallel Circuit www.bbc.co.uk

  4. Circuit 3: Series and Parallel Combo B A C Are all the bulbs the same brightness? Why? Which light bulb can you unscrew to have 1 bulb lit… 2 bulbs lit?

  5. Circuit 3: Series and Parallel Combo B A C Which bulb would be the brightest? Why? Which light bulb can you unscrew to have 1 bulb lit… 2 bulbs lit?

  6. B Circuit 3: More Series/Parallel Circuits A C Which light bulb can you unscrew to have 2 bulbs lit… 0 bulbs lit?

  7. Circuit 3: Parallel Circuit • You can unscrew any 1 light bulb and the other two will remain lit. • All the bulbs should be the same brightness

  8. Question 1 (brightness of bulb) • In parallel circuit: • Bulbs remain bright • In series circuit: • Bulbs become dimmer http://iss.cet.edu/electricity/

  9. Question 2: Series Circuit Resistance • What happens to the resistance of the circuit as more bulbs are added? • The resistance will increase (light bulbs are resistors) • How do you know? • The bulbs are not as bright … ↑R = ↓ I http://iss.cet.edu/electricity/

  10. Question 2: Series Circuit Resistance • If the resistance of each light bulb is 2 Ω the total resistance of the circuit is 6 Ω • If another 2 Ω light bulb is added the resistance of the circuit will be 8 Ω http://iss.cet.edu/electricity/

  11. Question 2: Parallel Circuit Resistance • What happens to the resistance of the circuit as more “branches” are added? • The resistance decreases – there are several paths for the current to follow(think about the difference in the flow of water out of a bucket with 1 hole in it verses several holes) • How do you know? • The bulbs are bright … ↓R = ↑I http://iss.cet.edu/electricity/

  12. Question 2: Parallel Circuit Resistance • If the resistance of each light bulb is 2 Ω the total resistance of this circuit is 2/3 Ω • If another branch is added with a 2 Ω light bulb the total resistance of this circuit would be ½ Ω (2/4 Ω) http://iss.cet.edu/electricity/

  13. Question 3:Series Circuit & Broken Bulbs • Why do all the lights turn off when one is unscrewed? • The path is broken – the current needs to go through each light bulb in order to flow (there is only 1 path for the current to take) www.bbc.co.uk

  14. Question 3: Parallel Circuits and Broken Bulbs • Why does one bulb stay lit when the other is unscrewed? • The current from the battery “splits” up to go through the different branches • The path to the other bulb is not broken – the current can take another path www.bbc.co.uk

  15. Question 4: Desired Type of Circuit for Decorative Strings of Light • Parallel • Why? • So the whole string does not go out when one bulb breaks (and the lights will be brighter)
