Across
- 2. A switch that makes or breaks a circuit based on the input or touch of the switch. When the switch is not depressed, the switch returns to its default status.
- 3. The “building block” of everything we know of on earth. Atoms are made up of protons, neutrons, and electrons.
- 6. A material made of atoms that transfer electrons easily.
- 10. A device that converts mechanical energy into electrical energy by using electromagnetic induction
- 11. The continuous flow through a component or an entire circuit.
- 12. A material attracted to any metal containing iron.
- 13. A restorable device that breaks the circuit if too much electrical current passes through it.
- 14. The flow of electrons in a conductor.
- 15. A material made of atoms that do not transfer electrons easily.
- 21. The type of charge an atomic particle has.
- 24. A filament that breaks the circuit if too much electrical current passes through it. It prevents damage to the rest of the circuit in the event of an overload.
- 27. The production of electricity in conductors with the use of magnets.
- 28. A terminal on a cell or battery.
- 29. A device used to check for continuous electron flow throughout an electrical circuit or through circuit components.
- 30. Electrons flow from a negative point to a positive point
- 32. A properly functioning circuit in which all loads are energized.
- 33. A liquid or paste that surrounds and touches electrodes, causing a chemical reaction between the electrodes and electrolyte, which produces an electrical current.
- 35. A switch used to control a load from two different locations.
Down
- 1. A material that is both a conductor and an insulator.
- 4. A switch used in conjunction with two single-pole, double-throw (SPDT) switches, allowing one or more loads to be controlled from three or more locations.
- 5. Wattage multiplied by the number of hours the wattage is used and then divided by 1000. It is the unit by which customers are billed for electricity usage.
- 7. A circuit or part of a circuit that is not energized.
- 8. A power source, a load, and conductors connected together so electrical current flows in a complete path.
- 9. A type of cell that cannot be recharged.
- 16. A drawing that traces the path electron flow will take in an electrical or electronic circuit. Symbols are included that represent the components in the circuit.
- 17. A measurement of electrical power calculated by multiplying voltage and amperage.
- 18. A device used to increase or decrease voltage supplied to a circuit.
- 19. A type of cell that can be discharged and recharged many times.
- 20. The outermost ring of electrons in an atom.
- 22. A device that can trip to open a circuit in case of an imbalance between the feed and return legs. It is designed to protect people and so is more sensitive than a circuit breaker or fuse and provides a quick reaction time.
- 23. A circuit in which the load is bypassed and the hot wire comes directly into contact with the return leg or with something grounded.
- 25. A common device for storing electrical power. A cell converts chemical energy to electrical energy.
- 26. A switch that makes or breaks one set of contacts to turn a load on and off.
- 31. The rate at which electrons move, or amperage.
- 34. Voltage (E) can be determined by multiplying current (I) by resistance (R).
