The disc has now changed its positionfrom Fig. 31 to Fig. 32. Conduit No. 2 is now positive and the currentflows as shown by the arrows. It can be seen that the polarity of the dis-charge has still been maintained, showing that all the positive ( +) impulsesare conducted along No. 3 and the negative (-) impulses along No. 4 ;thus giving absolute unidirectional current. The current is at all times luider perfect control of the operator. Theprimary winding of the transformer has five sections, each section allowing a 4 ^ -f^^.
