nating 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…
