Across
- 2. Any substance that has an absence of any electrical conduction.
- 3. is a point on the wave where the displacement of the medium is at a maximum.
- 5. disturbance (or oscillation) in a medium that is accompanied by a transfer of energy.
- 6. a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.
- 9. A form of mechanical wave where the oscillating particles in the medium move parallel to the direction of the wave.
- 14. A characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons.
- 19. The act or process by which an electric or magnetic effect is produced in an electrical conductor or magnetizable body when it is exposed to the influence or variation of a field of force.
- 20. A two terminal device which can maintain a fixed voltage
- 21. a unit of frequency, defined as the number of complete cycles of a periodic signal that take place in one second.
- 22. A substance that makes possible the transfer of energy from one location to another, especially through waves.
- 23. a periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.
- 26. A form of mechanical wave where the oscillating particles in the medium move perpendicular to the direction of the wave.
- 28. The process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size.
- 29. The proportional relation of current and electric field
- 30. A passive electronic component that stores energy in the form of an electrostatic field.
Down
- 1. is a region in a longitudinal wave where the particles are closest together.
- 4. the time needed for one complete cycle of vibration to pass a given point.
- 7. the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
- 8. The study of stationary electric charges or fields as opposed to electric currents.
- 10. The distance between successive similar points , such as crests, of a wave.
- 11. the change in direction of a wave passing from one medium to another caused by its change in speed.
- 12. A subatomic particle that is positively charged and can be found in the nucleus of every atom.
- 13. an electromotive force or potential difference expressed in volts.
- 15. A unit of measure of the rate of electron flow or current in an electrical conductor.
- 16. the change in direction of a wave-front at an interface between two different media so that the wave-front returns into the medium from which it originated.
- 17. A material that is neither a good conductor of electricity nor a good insulator, but has properties of electrical conductivity somewhere between the two.
- 18. the point on a wave with the maximum value or upward displacement within a cycle.
- 24. The measurement of electrical resistance between two points of a conductor
- 25. an object or type of material that allows the flow of an electrical current in one or more directions
- 27. The derived unit for electrical potential, electrical potential difference (voltage) and electromotive force.
