Electronic Currents - Vocabulary

1. Electric Current - a flow of electric charges. ( F12)
2. Circuit - a path that is made for an electric current (F12)
3. Electric cell - a device that supplies energy to move charges through a circuit. A battery is an electric cell.
4. Conductor - a material that current can pass through easily. Most metals are good conductors.(F13)
5. Insulator - a material that current cannot pass through easily. Plastic is an insulator. (F13)
6. Resistor - a material that resists but doesn't stop the flow of current. (F13)
7. Series Circuit - a circuit that has only one path for a circuit. (F14)
8. Parallel Circuit - has more than one path for current to travel. (F14)

Electronic Currents Study Guide

1. A flow of electric charges is called an __________________________.

2. A path that is made for an electric current is called a _____________________.

3. A battery is an ____________________, which supplies energy to move charges through a circuit.

4. A _____________________________ is a material that current can pass through easily.

5. A material that current cannot pass through easily is called an ______________________.

6. A material that resists but doesn't stop the flow of current is called a __________________.

7. A circuit that has ony one path for the current is called a _______________________ circuit.

8. A ______________________ circuit has more than one path for current to travel.

9. A ________________________ is a moving charge.

10. An electric current is measured in __________________.

11. An electric current needs a ______________________________ in order to flow.

12. The parts of the circuit system in a flashlight are _________________________, ________________.
________________________

13. If a part of the system is removed the circuit is  _________________ and the flashlight won't work.

14. The  _______________________________ in a circuit controls when a circuit is open or closed, and therefore controls the flow of electricity.

15. A current travels in a series circuit by following only _______________ path.

16. If there is one disconnected bulb in a  series circuit it will cause the other ligts to ________________ because there is only one path for the current to follow, and with one bulb out, the path is not continuous.

17. If you remove one bulb from a parallel circuit the other bulbs _____________________  because current continues to flow along a different path.

18. Your home is wired using ___________________________ circuits because if a bulb goes out, it does not prevent the rest of the electrical devices in the home from working.

19. The difference between a conductor and an insulator is that a current can flow easily through a _____________________ , but not through a(n) _____________________.

20. _____________________________  supply energy in electric currents.
