What reading level is Amateur Work volume 6 No 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
When dealing in such large numbers and using factors of safety of 3 or 4 it is necessary to estimate only approximately, and slide rule calculations are wholly adequate for most of the preliminary work.
Assume that the impregnated paper between the pies has a thickness of . 006 in. Per sheet. This insulation must withstand, for the method of connection which has been chosen, double the potential generated by a single pie. Or 6000 volts, roughly. From the accom- panying table it is seen that thi...s paper will rupture at 1200 volts per 1/1, 000 inch. Using a factor of safety of 4 there will be obtained 1800 volts per sheet, which would require four sheets between each pie or section.
The winding will 7iow take up (50 pies x 1/8 in. Each 7 1/2 in. And another 1/2 in. For the four end coils, making 8 in. Four thicknesses of paper x . 006 in. Per sheet x 64 coils = approximately 1 1/2 in. For the total thickness of the paper and 9 1/2 in. For the entire secondary. It has been found that a good length for the secondary might be considered that of the sparking distance of the coil if it is desired to err on the side of safety and have the least danger of the spark jumping inside of the secondary or across the surface.
