Physics Unit 2
Across
- 3. SI unit for electric current
- 6. States that for charged particles or objects that are small compared to the distance between them, the force between the charges varies directly as the product of the charges and inversely as the square of the distance between them
- 9. Flow of a charge always flows in one direction
- 11. Electronic device that restricts current to flow in a single direction
- 16. Energy a charge has due to its location in an electric field
- 19. Electric potential or potential difference measured in volts
- 22. Device for increasing or decreasing voltage through electromagnetic induction
- 23. The charging of an object without direct contact
- 24. Machine that produces electric current by rotating a coil within a stationary magnetic field
- 25. Electricity at rest
- 27. Any complete path along which charge can flow
- 28. Force field that fills the space around every electric charge or group of charges
Down
- 1. Measure of electrical resistance
- 2. Devices are arranged so that the current must flow through each device in order to complete the circuit
- 4. Rate at which energy is converted into another form of energy
- 5. Allowing charges to move freely along a connection between a conductor and the ground
- 7. Material that can be made to behave as either a conductor or an insulator
- 8. Material that has infinite conductivity at very low temperatures so that charge flows through it without resistance
- 10. Term applied to electric charge that has been redistributed on an object because of the presence of a charged object nearby
- 12. Electrons move in one direction and then in the opposite direction
- 13. Term applied to portions of an electric circuit that are connected at two points and provide alternative paths for the current
- 14. Material that is a poor conductor of electricity
- 15. Device used to store charge in a circuit
- 16. An atom or molecule in which the charges are aligned so that one side is slightly more positive or negative than the opposite side
- 17. Electric potential energy per coulomb at a location in an electric field
- 18. Devices are connected so that any device completes the circuit
- 20. SI unit of measurement for electric potential
- 21. Magnet with a field produced by electric current
- 26. Fundamental electrical property to which the mutual attractions or repulsions between electrons and protons is attributed
