1. Which type of circuit has more than one path for electricity to flow?
Parallel Circuit

2. What is this part of the bulb?
Filament

3. Is this an example of an insulator or conductor?

4. Which would conduct electricity best – a long wire or short wire?

5. How well an object conducts electricity depends on 3 things
How well an object conducts electricity depends on 3 things. What are they?
The material of an object
The length of an object
The width of an object

6. What happens to the remaining bulbs when 1 bulb burns out or is removed in a parallel circuit?
The other bulbs remain lit.

7. Which type of circuit has only one path for electricity to flow ?
Series Circuit

8. Is this an example of an insulator or conductor?

9. Which would conduct electricity best – a thin wire or wide wire?
A wide wire

10. What is another name for a nonconductor?
Insulator

11. What is this part of the bulb?
Base terminal

12. What happens to the brightness of a bulb if more bulbs are added in a parallel circuit?
The brightness remains the same

13. What is the job of the filament in a bulb?
It transforms electrical energy into light energy.
It also connects the support wires.

14. What is the point on a battery or bulb that must be touched in order to make a circuit complete?
Terminals

15. What happens to the brightness of a bulb if more bulbs are added in a series circuit?
The bulbs get dimmer

16. What would the voltage be in the parallel circuit below?
1.5 volts

17. In which circuit is it easier to find a burned out bulb – series or parallel?
Parallel Circuit

18. What is the name of a material that does not allow electricity to easily pass through it?
Insulator

19. What is this part of the bulb?
Side terminal

20. Is this an example of an insulator or conductor?

21. What is the difference between a series and a parallel circuit ?
Parallel Circuit – more than I path for electricity
Series Circuit – I path for electricity

22. What happens to the remaining bulbs when 1 bulb burns out or is removed in a series circuit?
The other bulbs go out.

23. If a bulb in a circuit does not light, what could be the problem?
Batteries not
connected properly
Dead battery
Open switch
Broken bulb

24. Why would a circuit wired with batteries have a brighter bulb
than a circuit wired with
batteries ?
The circuit with +-+- gets voltage from 2 batteries. The circuit with only gets voltage from 1 battery. 2 of the batteries with the negative sides together cancel each other out.

25. What would the voltage be in the series circuit below?
4.5 volts

26. What happens if 3 batteries are connected in a series circuit
and 1 battery is connected
backwards?
2 batteries will cancel each other out
leaving only the voltage from 1 battery

27. What material is the best conductor of electricity ?
Metal

28. What is an open circuit? Circuit through which electricity does
not flow because one part is not
connected.
