Unformatted text preview: Power Distribution System devised by Nikola Tesla discuss feud between Edison and Westinghouse, ac vs. dc plants Chapter 20 Notes College Physics by Giambattista et al. John B. Ross, Ph.D. IUPUI Physics Dept. Advantages of AC Power: cheaper and easier to generate adapt transformers transmit less heat loss may be rectified cheaply converted to dc power Transformers iron core primary coil secondary coil E 1 E 2 N 1 N 2 Primary generates an ac magnetic field causing an induced emf in the secondary. The change in flux through the primary equals that of the secondary so 1 2 1 2 N N E E (by flux conservation) I 1 E 1 = I 2 E 2 (by energy conservation)...
