Across
- 1. using a force to move a charged particle by an electric field
- 5. law relating voltage difference, electric current flow, and resistance of path of current, V=IR
- 7. a unit of electric current equal to a flow of one coulomb per second
- 9. SI unit of electromotive force(difference of potential that would drive one ampere of current against one ohm resistance)
- 11. the path that electrons from a voltage/current source flow
- 12. process where a conductor placed in a changing magnetic field(or conductor moves through stationary magnetic field) causes production of a voltage across the conductor
- 13. an electromotive force(difference of potential that would drive one ampere of current against one ohm resistance) or potential difference expressed in volts
- 14. form of energy resulting from existence of charged particles either statically as an accumulation of charge or dynamically as a current
- 15. electrical component/portion of a circuit that consumes electric power i.e. appliances & lights
- 17. useful power output divided by total electrical power consumed
Down
- 2. measure of difficult to pass an electric current through a conductor
- 3. a closed circuit where current divides into two or more paths before recombining to complete the circuit
- 4. rate, per unit time, which electrical energy is transferred by an electric circuit
- 5. SI unit of electrical resistance expressing resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt
- 6. an electric charge that lets work be accomplished either statically as an accumulation of charge or dynamically as current
- 8. flow of electric charge
- 10. a closed circuit where current follows one path
- 11. contains electric charges(electrons) relatively free to move through the material
- 16. power derived from utilization of physical or chemical resources(esp. to provide light and heat or to work machines)
