of the coils contains a num-ber of turns of fine wire, while the other contains onlya few turns of large wire. When an alternating cur-rent is sent around the coils of fine wire, generallycalled the primary, a current will be induced in thecoil of heavy wire, or secondary. The amount of cur-rent… … FIGURE 76. between the large and the small wires. To illustrate,suppose we had a current of 10 amperes at a pressureof 1,000 volts in the primary, and there were ten timesas many turns of wire in the primary coil as in thesecondary, then we would get a current of ioo amperesat a pressure of ioo…
