Across
  1. 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.
  2. 5. - The standard unit of measure used for electric power.
  3. 6. law - A law of physics that describes the relationship between voltage, current, and resistance using the equation V = IR.
  4. 8. - An electronic component that only allows current flow in one direction.
  5. 11. - A device that stores and produces electricity from chemical cells.
  6. 12. circuit - is a collection of electronic components connected by a conductive wire that allows for electric current to flow.
  7. 13. - The standard unit of measure for capacitance.
  8. 15. - A material in which an electronic charge does not flow freely and does not conduct the flow of electric current.
  9. 16. current - is the flow of electric charge through a material. The standard unit for electric current is the ampere.
  10. 17. - An electrical component that transfers electrical energy using inductive coupling between two winding circuits.
  11. 19. current A type of current that only flows in one direction (unlike AC which periodically reverses direction).
  12. 22. - The standard unit of measure for resistance.
  13. 23. law - A law of physics that describes the electrostatic interaction between charged particles.
  14. 24. - A semiconductor device used in an electric circuit to regulate current flow to act as a gate, switch, or amplifier for electronic signals.
  15. 25. field - The magnetic influence produced by electric currents and magnetic materials.
  16. 27. current An electric current that reverses direction on a periodic basis. It is widely used to transport power on power lines.

  1. 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. 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.
  3. 4. - A material that allows the free flow of electric charge. Copper wiring is the most widely used electrical conductor.
  4. 7. - The standard unit of measure for inductance.
  5. 9. - A basic subatomic particle found in all atoms, electrons carry electricity by flowing from one atom to the next in a conductive material.
  6. 10. - A basic electrical component that stores electric charge. Capacitors are made from two electrical conductors separated by an insulator.
  7. 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.
  8. 18. - A basic electronic component that prevents the flow of electric current.
  9. 20. - A material that behaves between a conductor and an insulator depending on the conditions. Silicon is a widely used semiconductor in electronics.
  10. 21. - The standard unit of measure for electric potential (voltage).
  11. 26. - The standard unit of measure of electric current. It is sometimes written as amp.
