Electricity

1. The measured value of one value keeps the same ratio as the value of the second value.
8. A mathematical expression that describes the relationship between voltage, current, and resistance.
9. A material that is neither a good conductor nor a good insulator.
13. The pressure on electrons to move them through a conductor that is supplied by the power source.
14. An electrical device designed to open when a current flow exceeds a limit.
15. An electrical circuit that contains both a series circuit and a parallel circuit.

2. The scientific principle that states that like magnetic poles repel and unlike magnetic poles attract.
3. The measure of the attraction that an atom has for the electrons orbiting about its nucleus.
4. A component of an electrical circuit which consumes power.
5. An electrical circuit in which the electrons have more than one pathway to follow.
6. An electrical pathway in which electrons travel.
7. A metal core that is rendered magnetic by the passage of an electric current through a surrounding coil.
10. The flow of electrons through a pathway.
11. The electron on an atom’s outermost orbit.
12. An electric circuit that contains only one path for current to flow.
