1. For the device to be built high quality steel is needed.
2. It is important for the device to be cooled.
3. A transformer is used in order for the voltage to be changed.
4. For the transformer to step up voltage its secondary winding should have\nmore turns than the primary.
5. In order for the generator to operate properly it is essential to cool it.
6. Autotransformers are used for voltage to be transformed within small ranges.
7. For a wire to be a good conductor it is to be made of low resistance metal.
8. For the oil to be used as an insulator, it is necessary to remove all moisture\nfrom it.
9. For the leakage flux to be reduced the windings of the transformer should be\nplaced as close as possible.
10. For electric power to be used economically we must use different\ntransformers.
