Lesson 2 Electricity Basics

3. Essentially, a measure of the work associated with moving an electric charge from one point to another.
4. A labeled drawing that explains or shows the parts of something.
6. A form of potential energy that is stored in chemical bonds.
8. An instrument used to measure electric current in a circuit.
9. The net movement of electrons through a conductor.
11. A circuit in which current flows in more than one closed path
14. A circuit in which current flows only in one closed path.
16. A scientific investigation in which one variable (the independent variable) is hanged, and all others are controlled, or kept the same.
18. An element or device in an electric circuit.
19. An instrument that measures electrical potential, or voltage, across a component or
21. The variable in an experiment that the experimenter purposefully changes in order to determine its effect.
22. A device containing an electric cell or a series of electric cells storing energy that can be converted to electrical power.
23. A proposed explanation for an observation based on previous information that s used as a starting point for an experiment.
24. A continuous conducting path for current.
25. Any factor that could affect the results of an experiment.

1. A group of objects that function together as one unit
2. Unit of electric current.
5. The line integral of magnetic field around a closed path is equal to the product of the magnetic permeability of that space and the total current through the area bounded by that path.
7. A form of kinetic energy that involves the transfer of change through an electrical conductor.
10. The variable in an experiment whose value is determined by the experiment.
12. The presence or flow of electric charge.
13. Unit of electrical potential.
15. A diagram that represents an electric circuit using symbols.
17. To make an educated guess about the outcome of a situation.
20. A circuit in which current flows only in one closed path.
