- 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.
That swing analogy is golden-thank you sir
He's undoubtedly the best Physics teacher ever!
Oh my god
That was one of the best lessons I've got, thank you so much
this man emanates pure wholesomeness
Best concept ever! Loved it!
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?
Awesome video! Thank you!
thank you very much professor, that was an excellent explanation.
Finally, we see how scientists derive new equations in class.
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.
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 ruclips.net/video/SE-AiC9yiFc/видео.html
Hats off . Thank you so much sir.
nice one. thank you.
Thank you.
That was amazing ❤️❤️❤️❤️
Realy ?
Nice explanation😚
that graph was v helpful
YES!!!!!
I must impressed by indian sir
Sachin sir physics. Chanel
Kya padhate hai
Thanxxxxx sir
How do yo?
27000MHZ something happened ....
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 !
