Across
- 3. Unit of current. The charge that flows during one second
- 5. Unit of electric charge
- 8. A component made of a thin wire that protects a circuit from electrical fire. If the current gets too large, the fuse wire melts (the fuse 'blows') and stops the current.
- 14. A Component which changes electrical energy into light energy
- 15. unit of power
- 16. A material with high resistance and that doesn’t let electricity pass through
- 17. Used in a circuit when there is more than one cell
- 18. a material that always lets electrical current to pass through
- 20. A piece that only lets electricity flow in one direction
- 21. Describes a circuit in which the current travels along one path through every component.
- 22. A component in a circuit. When closed the current can flow. When open the current cannot flow.
Down
- 1. the unit of resistance
- 2. A meter that is used to measure the voltage of a circuit
- 4. Describes a circuit in which the current splits up into more than one path.
- 6. Flow of electric charge. Measured in Amps. The number of coulombs of charge that flow per second.
- 7. A very thin piece of wire inside a lamp that glows and gets hot when current passes through it
- 9. A component which changes chemical potential energy to electrical energy.
- 10. The measurement of how hard it is for electricity to pass through a wire
- 11. an electrical device that has a specific definition
- 12. the flow in a circuit that makes a current
- 13. amount of energy transferred every second
- 19. current current that only flows in only one direction
- 23. something that changes chemical potential energy into electrical energy
