Across
- 3. charge - This is a basic characteristic of matter that is based on the balance of protons (positive charge) and electrons (negative charge). The standard unit for electric charge is the coulomb.
- 5. - The standard unit of measure used for electric power.
- 6. law - A law of physics that describes the relationship between voltage, current, and resistance using the equation V = IR.
- 8. - An electronic component that only allows current flow in one direction.
- 11. - A device that stores and produces electricity from chemical cells.
- 12. circuit - is a collection of electronic components connected by a conductive wire that allows for electric current to flow.
- 13. - The standard unit of measure for capacitance.
- 15. - A material in which an electronic charge does not flow freely and does not conduct the flow of electric current.
- 16. current - is the flow of electric charge through a material. The standard unit for electric current is the ampere.
- 17. - An electrical component that transfers electrical energy using inductive coupling between two winding circuits.
- 19. current A type of current that only flows in one direction (unlike AC which periodically reverses direction).
- 22. - The standard unit of measure for resistance.
- 23. law - A law of physics that describes the electrostatic interaction between charged particles.
- 24. - A semiconductor device used in an electric circuit to regulate current flow to act as a gate, switch, or amplifier for electronic signals.
- 25. field - The magnetic influence produced by electric currents and magnetic materials.
- 27. current An electric current that reverses direction on a periodic basis. It is widely used to transport power on power lines.
Down
- 1. - A basic passive electrical component that resists changes in electric current. Inductors are generally made by winding or coiling a wire, sometimes around a magnetic core. The unit of measure for an inductor is the Henry.
- 2. electricity - The build up of an electric charge on the surface of an object. The charge remains in one area rather than flowing to another area.
- 4. - A material that allows the free flow of electric charge. Copper wiring is the most widely used electrical conductor.
- 7. - The standard unit of measure for inductance.
- 9. - A basic subatomic particle found in all atoms, electrons carry electricity by flowing from one atom to the next in a conductive material.
- 10. - A basic electrical component that stores electric charge. Capacitors are made from two electrical conductors separated by an insulator.
- 14. potential - is the difference in electrical charge between two points in a circuit. It is also called the voltage. The standard unit for electric potential is volts.
- 18. - A basic electronic component that prevents the flow of electric current.
- 20. - A material that behaves between a conductor and an insulator depending on the conditions. Silicon is a widely used semiconductor in electronics.
- 21. - The standard unit of measure for electric potential (voltage).
- 26. - The standard unit of measure of electric current. It is sometimes written as amp.
