CH8 Electrical

2. A material made of atoms that transfer electrons easily.
4. A device used to increase or decrease voltage supplied to a circuit.
7. A switch that can provide variable motion control. It can vary the resistance within the switch, which affects both the current and voltage flowing out of the switch.
9. A terminal on a cell or battery.
12. A circuit in which the load is bypassed and the hot wire comes directly into contact with the return leg or with something grounded.
14. A properly functioning circuit in which all loads are energized.
19. The type of charge an atomic particle has.

1. A device used to check for continuous electron flow throughout an electrical circuit or through circuit components.
3. A measurement of electrical power calculated by multiplying voltage and amperage.
5. A material that is both a conductor and an insulator.
6. A material made of atoms that do not transfer electrons easily.
8. Voltage (E) can be determined by multiplying current (I) by resistance (R).
10. A liquid or paste that surrounds and touches electrodes, causing a chemical reaction between the electrodes and electrolyte, which produces an electrical current.
11. A restorable device that breaks the circuit if too much electrical current passes through it.
13. A device that converts mechanical energy into electrical energy by using electromagnetic induction.
14. The flow of electrons in a conductor.
15. A circuit or part of a circuit that is not energized.
16. A common device for storing electrical power. A cell converts chemical energy to electrical energy.
17. The continuous flow through a component or an entire circuit.
18. The “building block” of everything we know of on earth. Atoms are made up of protons, neutrons, and electrons.
