ating current is sent around the coilsof fine wire^ generally called the primary^ a current will beinduced in the coil of heavy wire^ or secondary. The amountof current induced in the larger wire will be relativelygreater in amperes^ and less in potential than that of thefine wire circuit.- This… … Fig. 583 primary, and there were ten times as many turns of wirein the primary coil as in the secondary^, then we would geta current of 100 amperes at a pressure of 100 volts in thesecondary coil. This same relation would hold true what-ever the ratio between the number of turns on the twocoils…
