CH 11 & 12 Starkey
Across
- 2. the maximum extent of a vibration or oscillation, measured from the position of equilibrium
- 3. is the difference in potential between two points in an electric field
- 5. the negatively charged electrode by which electrons enter an electrical device
- 6. the application of carefully controlled charge current pulses into the battery
- 9. the positively charged electrode by which the electrons leave a device
- 12. responsible for the chemical bonds between atoms which create molecules, and intermolecular forces
- 14. the interval between the time, during the first transition, that the amplitude of the pulse reaches a specified fraction of its final amplitude, and the time
- 15. electrical circuit that is not complete
Down
- 1. is the difference of electrical potential between two points
- 4. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies
- 7. an electric current that is uni-directional, so the flow of charge is always in the same direction
- 8. one that is complete, with good continuity throughout
- 10. stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids
- 11. where the power transfer is constant during each electrical cycle
- 13. periodic current which changes in value but never changes direction
