ropernumber. The thickness of three layers will be 3X0.142, or0.426 inch, so that the width of the shoulder of the wooden endsfor the primary coil forms should be 0.42 inch. The ends maybe made of wood i inch thick and may be glued to the card-board cylinder. Winding Secondary. The secondary will… … Fig. 25. Device for Winding Primary Coil wound in a number of sections, or coils, so that the pressureper coil is greatly reduced. Since the secondary will encircle the primary, it will be dis-tributed over the two legs of the transformer as is the primary.The pressure of 10,000 volts will…
