Electricity Vocab

1. property of matter (like electrons or protons) that causes electrical effects; can be positive or negative
2. Another term for electric potential difference; the "push" that moves electric charges in a circuit
4. The push or pull between electric charges
6. The unit used to measure electric resistance
8. An electric current that flows in only one direction
9. A rule stating that current equals voltage divided by resistance (I = V/R)
11. An electric current that changes direction back and forth regularly
12. A material (like copper) that lets electric current flow easily.
13. The amount of electric potential energy per unit charge at a point, measured in volts
15. The unit used to measure electric current
16. A circuit where components are connected end-to-end, so current flows through each one in turn
17. A device that stores and releases electrical energy in a circuit.
18. The unit used to measure electric potential or voltage
19. The rate at which electrical energy is used or produced, measured in watts

1. A complete path that allows electric current to flow.
3. A material’s opposition to the flow of electric current
5. The difference in electric potential (voltage) between two points in a circuit
7. The flow of electric charge through a conductor
10. circuit where components are connected across common points, so current can flow in multiple paths
14. drawing that uses symbols to show how a circuit is put together
