tion in the open core transformer is not exactly m proportionto the turns, due to magnetic leakage. The design is, therefore, altered to meet theseconditions. Generally the secondary is given more turns than the usual transformer equation would require. . . ■ -c- in -, The so-called auto… … Fig. 39—^Auto Transformer. used for both circuits. A portion of the current flowing in the secondary winding is in-duced by the passing of the flux through the core from the primary turns, but anotherportion flows into the secondary circuit by direct conduction. Although transformers of this type…
