Electricity Vocab

5. Current – The flow of electric charge through a wire or circuit.
7. Power – The rate at which electrical energy is used or transferred.
8. – The unit used to measure voltage (potential difference).
10. Current– Electric current that changes direction back and forth over time.
12. – A property of matter (positive or negative) that causes electrical forces.
14. – The “push” that makes electric charges move through a circuit.
16. – A material that allows electricity to flow easily (like metal).
17. – The unit used to measure electrical resistance.
19. Diagram – A drawing that uses symbols to show how a circuit is arranged.
20. Circuit – A circuit with multiple paths for current to flow.

1. Force – The force between charged objects (attraction or repulsion).
2. Current – Electric current that flows in only one direction.
3. – A complete path that electricity flows through.
4. Difference – The difference in electrical potential between two points (also called voltage).
6. Potential – The potential energy per charge at a point in a circuit.
9. – A device that stores electrical energy temporarily.
11. Circuit – A circuit with only one path for current to flow.
13. Resistance – How much a material opposes the flow of electric current.
15. Law – A rule that relates voltage, current, and resistance (V = IR).
