Across 2. The difference of electrical potential between two points 3. A region around a magnetic material or a moving electric charge within which the force of magnetism acts 6. An electric current flowing in one direction only 9. A device having a designed resistance to the passage of an electric current 11. An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies 15. Supply (a device) with mechanical or electrical energy 17. Concentrated or lumped resistance that would cause the same power loss as the actual small resistance values distributed throughout a circuit 19. Induced electromotive force in any closed circuit is equal to the rate of change of the magnetic flux through the circuit 21. Makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages 22. A region around a charged particle or object within which a force would be exerted on other charged particles or objects 23. A substance or device that does not readily conduct electricity 24. The SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance

Down 1. Production of an electromotive force across a conductor when it is exposed to a varying magnetic field 4. A unit of electric current equal to a flow of one coulomb per second 5. An electromotive force or potential difference expressed in volts 7. A dynamo or similar machine for converting mechanical energy into electricity 8. Of or relating to the interrelation of electric currents or fields and magnetic fields 10. The current divides into two or more paths before recombining to complete the circuit 12. Each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically 13. The individual magnetic moments of the atoms are aligned with one another and they point in the same direction. 14. The current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths 16. An object or type of material that allows the flow of electrical current in one or more directions 18. A machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts 20. 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
