SET 8

5. the effects produced by moving charges.
7. the time rate of flow of electric charge.
12. Light which produces heat and has a long wavelength, penetrating deeply.
13. in the direction in which positive charges would flow.
14. is equal to one joule per coulomb (J/q).
15. the unit of electric current.
16. the unit of resistance.

1. If a separated charge were free to move, then it would move toward the charges of sign.
2. there is not a complete path or circuit through which charge can flow and there is no current.
3. materials that are neither good conductors nor good insulators.
4. the net flow of charge is characterized by an average velocity.
6. materials in which electric charge flows readily.
8. this opposition to the flow of charge.
9. is defined as the amount of work it would take to move a charge between two points divided by the value of the charge.
10. materials in which electrons are more tightly bound and they do not conduct electricity very well.
11. An apparatus that changes alternating current to direct current.
