Across
- 4. short for ampere.
- 5. stable, negatively charged elementary subatomic particle found orbiting the nucleus of an atom in shells
- 8. substance which does not readily allow the passage of heat or sound.
- 9. the SI unit of electromotive force, defined as the potential difference between two points on a conducting wire carrying a current of one ampere
- 12. physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
- 14. electrical circuit that is not complete.
- 15. the buildup of an unbalanced electrical charge on the surface of a material, typically caused by contact and separation (friction) between different materials
- 16. a roughly circular line, route, or movement that starts and finishes at the same place.
- 17. complete, uninterrupted electrical path that allows electric current to flow continuously from a power source through components and back to the source
- 18. occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder
Down
- 1. an electric current that periodically reverses direction and changes its magnitude continuously with time
- 2. material that allows electricity or heat to flow through it easily, characterized by low electrical resistance and freely moving electrons
- 3. electrical configuration with multiple, branched paths for current to flow, where all components are connected across the same two nodes
- 5. form of energy resulting from the existence of charged particle
- 6. the unidirectional, consistent flow of electric charge in a single direction
- 7. belonging to the present time; happening or being used or done now.
- 10. SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
- 11. refusal to accept or comply with something; the attempt to prevent something by action or argument
- 13. an electrical circuit where components are connected end-to-end, forming a single path for current to flow, meaning the same current passes through every component
