Across
- 2. The electrical "pressure" or force that pushes current through a circuit.
- 7. rate at which electrical energy is transferd by an electric cirut
- 8. A material ( like copper or aluminum) that allows electricity to flow through it easliy
- 10. A physical property of matter ( positive/ negative) that causes it to experience a force when place in an electromagnetic field
- 11. The measure of how much a material opposes the flow of electric current
- 14. The unit of measurements for electrical resistance
- 15. The amount of potential energy per unit charge at a specific point in an electric field
- 16. A circuit with multiple paths for current to flow;if one path breaks, others keep working.
- 18. Electric current that flows only in one direction
- 19. Electric current that revereses its direction many times a second at regular intervals.
- 20. The formula stating that current equals voltage divide by resistance
Down
- 1. A.K.A voltage that difference in electric potential between 2 points
- 3. The continuous flow of electric charge through a conductor
- 4. A device used to store an electric charge,consisting of one or more pairs of conductors sperated by an insulator
- 5. A simplified drawing using symbols to repersent the components and connections in an electric ciruit
- 6. The attractive or repulsive force between 2 charged objects
- 9. A complete, closed path through which electric current can flow
- 12. A circuit where components are connected in a single loop; if one part breaks, the whole circuit stops
- 13. Unit of measurements for voltage/ potential differnece
- 17. The standard unit of measure for electric current ( the flow of electrons)
