Across 1. Most transformers are known as this type 4. Name given to losing some of the magnetic flux 6. Metal structure on which the windings are wound 11. Name given to several loops of wire 12. Output voltage less than input voltage 16. Current flowing in the windings produce this 17. Percentage difference between no load & full load output voltage 21. Core is made up of thin slices of steel known as 23. All transformers have to be provided with some form of this 24. Magnetic loss in transformer caused by core material 27. Process by which all transformers work 28. Name given to winding connected to the supply 29. Output voltage greater than input voltage 30. Name given to the number of coils on the winding

Down 1. Type of insulation on the windings 2. Part of transformer on which the windings are wound 3. Load is connected to this winding 5. No machine is 100% of this 7. Winding to which load is connected is sometimes know by this name 8. Name given to primary and secondary conductors 9. Name given to the inductance between two coils 10. These occur in all transformers and all machines 13. Name given to the circuit connected to the secondary winding 14. Transformers will only work on this type of supply 15. Type of transformer construction 18. Type of safety transformer 19. Another name for voltage 20. Winding to which the supply is connected is sometimes known by this name 22. Links both windings 23. Flows in the windings when load connected 25. Type of loss reduced by laminations 26. Name given to the magnetic losses

The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.
