This video covers Section 23.4 of Cutnell & Johnson Physics 10e, by David Young and Shane Stadler, published by John Wiley and Sons. The lecture is part of the course General Physics - Life Sciences I and II, taught by Dr. Boyd F. Edwards at Utah State University. This video was produced through the support of the USU Physics Department and the USU Media Productions team.

Dual resonant coils (both primary and secondary resonant and loose coupled), Have 2 resonant modes. When comparing the voltage or current of the 2 coils, the first mode is in phase. While the second higher frequency mode, is 180 degrees out of phase. Partly this is explained by frequency splitting, but why do the phases change?

Oh my god That was one of the best lessons I've got, thank you so much

Finally, we see how scientists derive new equations in class.

Система "равновесная" , какого хрена конденсатор выбран начальной и конечной точкой сжатия пружины ? - если это параллельный резонанс то это глупо , полюса меняются местами , представление не правильное а без него не понять физическую сущность процесса , формулы никогда не дадут понять суть !

electric resonance simply explained: The electric field energies transform back and forth, changing their polarities while doing so. While the capacitor discharges its (di)electric field, it charges up the coil with magnetic field energy. and while the coil magnetic field discharges, it charges up the (di)electric field of the capacitor. This cycle continues until resistance has transformed the energy into heat.

thank you very much professor, that was an excellent explanation.

Resistance transforms energy into heat? I'm not sure how 'energy' is defined, but resistance/friction controls how fast current flow. Heating or lighting is a by-product of current flowing thru resistance. Electrons do not get consumed. The very simple capacitors shuffling demo proves that here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SE-AiC9yiFc.html
