Across
- 5. How difficult it is for current to flow through a component in a circuit.
- 9. A circuit in which there are two or more paths or branches for the current.
- 10. A negatively charged particle found in atoms. They flow through a wire when a current flows.
- 14. A measure of the push of a cell or battery, or the energy that the cell or battery can supply.
- 15. The pathway through witch electrical current flows
- 19. Two or more electrical cells joined together.
- 20. A device for measuring electric current in a circuit.
- 21. The unit of resistance, symbol Ω.
- 22. A property of a material or particle that can be positive or negative. Measured in Coulombs.
- 23. A material that conducts charge or energy well, such as a metal or graphite.
- 24. A device for measuring voltage.
- 26. A component that controls the current by making or breaking the circuit.
- 27. A chemical store of energy, which provides the push that moves charge around a circuit.
Down
- 1. Units of measurement of electric current, symbol A.
- 2. A positively charged particle found in atoms.
- 3. Imaginary lines that show the direction of the force on magnetic material. They can be investigated by putting compasses around a magnet or by putting iron filings around a magnet.
- 4. Be pushed away from each other
- 6. Be pulled together
- 7. A temporary magnet produced using an electric current.
- 8. A circuit in which components are joined in a single loop.
- 11. Units of measurement of voltage, symbol V.
- 12. A measure of the potential difference of a cell or battery used to send a current around a circuit.
- 13. A neutral particle found in atoms.
- 16. A material that does not conduct electricity or transfer energy well.
- 17. The flow of electrical charge (electrons) around a complete circuit per second.
- 18. electricity: A buildup of charges on an object
- 25. A component or machine that spins when a current flows through it.
