 From the list of words above, choose the one that corresponds to the definitions below.

1. The SI unit of charge. Equivalent to the magnitude of charge resulting from 6.25 x 1018 electrons _________________________

2. A device placed in line with the current in a circuit in order to measure the circuit's current. _________________________

3. A material or object that generally prevents the flow of energy. _________________________

4. An arrangement of components that allows for the flow of electricity. Usually composed of at least one cell, conducting wires, and a resisting material.

5.  A material that easily allows the flow of energy. _________________________

6. The process of charging an object by direct contact with a charged object. _________________________

7. The process of charging an object by bringing a charged object near._________________________

8. The process of charging an object by "scraping" electrons from one object onto another. _________________________

9. A force field that exists in  the space surrounding every electric charge or group of charges. _________________________

10. A force field that exists in  the space surrounding every magnet or current carying wire. _________________________

11. The SI unit of potential difference. _________________________

12. The current in a circuit is directly proportional to to the voltage in the circuit, and is inversely proportional to the resistance of the circuit. V = I x R_________________________

13. The difference in electric potential between to points. Also known as voltage. _________________________

14. A device for increasing or decreasing voltage through elegtromagnetic induction. _________________________

15. The resulting flow of matter or energy; specifically electric charge here. _________________________

16. The opposition of a material to the flow of electric current through it. _________________________

17. A buildup of electric charge in a particular location. More appropriately called electrostatic charge. _________________________

18. The SI unit of resistance. Defined as one joule per coulomb. _________________________

19. The rate at which electrical energy is converted into another foerm such as light, heat, or mechanical energy. _________________________

20. A device used to indicate the presence of charged particles; usually consists of two small strips of metal foil suspended from a conducting material.  _________________________

21. A microscopic cluster of atoms with aligned magnetic fields, the entire cluster then behaves as a tiny magnet. _________________________

22. Material that has infinite conductivity at very low temperatures (~0 - 100 K), so that charge flows through it without resistance. _________________________

23. Electric current in which the charge flows in one direction through the circuit. _________________________

24. Electric current that repeatedly reverses direction, twice each cycle. _________________________

25. A source of electric potential allowing charges to flow. Most commonly results from the reaction of a metal with an acid and used in automobile batteries. _________________________

26. A source of electric potential allowing charges to flow. Most commonly results from the reaction of a metal with solid paste; are often called batteries like the ones you use in a flashlight. _________________________

27. A series of cells (wet or dry) used to produce current in a circuit. _________________________

28. The SI unit of electric current. Defines as the flow of one coulomb of charge per second._________________________

29. Any object that has the ability to produce a magnetic field. Will attract objects containing iron, cobalt, or nickel. _________________________

30. A strong, short-lasting magnet that can be made by inserting iron into a wire coil that is conducting an electric current. _________________________

31. A device connected across a circuit component to determine the potential difference it experiences. _________________________

32. An electric circuit in which devices are connected to the same two points of the circuit, so that any single device completes the circuit indrpendently of the others. If one light goes out the others stay lit. _________________________

33. An electric circuit in which devices are arranged so that charge flows through each in turn. If one part of the circuit is removed or breaks, the entire circuit is broken. If one light goes out, they all go out. _________________________

34. Machine that produces electric current, usually by rotating an a coil of wire within a stationary magnetic field. _________________________

35. A machine that produces mechanical energy through the interaction of a stationary magneic field and a current carrying coil of wire. _________________________

36. The ability to produce a magnetic field and attract magnetic materials. _________________________

37. The phenomenon of inducing a voltage in a conductor by changing the magnetic field near the conductor. _________________________

38. One of the regions on a magnet that produces a magnetic field. The geographic north is actually the south. _________________________
