Across
- 3. negatively charged subatomic particle which orbits the atom’s nucleus
- 5. Effect building of electric charge generated by friction
- 6. movement of electrons carrying energy
- 11. scientific principle explaining the relationships among voltage, resistance and current in a conductor; expressed as Volts = Amps x Ohms, Amps = Volts/Ohms or Ohms = Volts/Amps

- 4. closed path in which electric current flows
- 7. ratio of true power used to do work to apparent power supplied to the circuit
- 8. unit of measurement for electrical resistance
- 9. unit of measurement for electric current; one coulomb per second equals one ampere; often abbreviated to ‘amp’
- 10. pressure(energy) put on free electrons causing them to flow
- 13. electricity which is not moving; caused by the triboelectric effect
- 18. unit of measurement for electric power
