3. SERIES CIRCUIT
This series circuit includes 2 bulbs, 3 wires and 1 D cell battery.

4. SERIES CIRCUIT
Create a schematic using symbols to depict this circuit.

5. SERIES CIRCUIT @ L2 L1 @

6. SERIES CIRCUIT Single path of electricity
When 1 light goes out, all go out
Add more resistors, all lights get dimmer

7. PARALLEL CIRCUIT
This parallel circuit has 2 bulbs, 4 wires and a battery.

8. PARALLEL CIRCUIT
Create a schematic using symbols to depict this circuit.

9. PARALLEL CIRCUIT @ L1 @ L2

10. PARALLEL CIRCUIT
Many paths of electricity
When 1 light goes out, the rest stay on
Add more lamps, brightness does not change

20. Is this circuit Series or Parallel?@

21. Parallel…How do you know?@

22. Parallel…because there is more than 1 path of electricity.@

23. What are the 4 keys to differentiating between parallel and series?
