Across
- 2. the 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.
- 4. a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
- 7. a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
- 9. the SI base unit of electrical current.
- 10. the refusal to accept or comply with something; the attempt to prevent something by action or argument.
- 12. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
- 14. A series circuit is one in which all circuit elements are arranged in a single path.
- 15. the interaction of electric currents or fields and magnetic fields. the branch of physics concerned with electromagnetism.
- 16. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
Down
- 1. filled with excitement, tension, or emotion.
- 3. a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
- 5. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- 6. a roughly circular line, route, or movement that starts and finishes at the same place.
- 8. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
- 11. the strength and vitality required for sustained physical or mental activity.
- 13. an electric current flowing in one direction only.
