I just realized that I missed this chapter for homework and am now trying to frantically complete all of it plus another chapter in one day. Your video helps so much. Idk why teachers don't teach this this way, it makes so much more sense like this.
Good video, the only thing is that I wish you used some example problems where we need to use the equations as they're written using limits of integration
I am pretty sure that the transfer of energy between two plates in a capacitor is through dielectric induction, which is a form of longitudinal wave (not a hertzian wave), which means there is NO electromagnetic field generated. The only time you have an electric field is when you have a hertzian waveform. An example of a longitudinal electromagnetic waveform is one that is generated between the torus and the Earth in a Tesla coil. Again there is no magnetic field generated from the longitudinal wave. The reason for this is the longitudinal wave vibrates in the same direction as it travels, where is a Hertzian wave vibrates at a 90 degree angle from the direction of the wave.
How do you differentiate between average and total power (ref? Q11) because on first glance I thought the 500W was the total power so I had to find ½ of that as average power before dividing by area
