Up 🙂. I just want a confirmation of my last reply.

Yes, one of the assumptions of my experiment is that it is not connected to a battery. In that case, does my conclusion that there is no variation in electric flux make sense? It starts with a flux ##EA## and ends with ##EA##. In the case you mention that it is connected to a battery, I...

Thank you, I have already modified the nomenclature to avoid confusion with the differential elements. The equality that confused me is the following: I think I got it now, as the area of the plates increases both equations give zero. The first equation gives zero because the electric flux does...

When a current flows into or out of the capacitor plates, a magnetic field is created between them. Even though there are no charges flowing in the space between the plates, there is still a magnetic field and the source of that field is an uncharged current called a “displacement current”...

Thank you both for your vocation @sophiecentaur @DaveE

Thanks, it was much clearer to me. Even though the first image does not make sense, could it be said that at the beginning of the charging of a capacitor there is a potential difference between the positive terminal of the battery (negative) and the positive (negative) plate of the capacitor...

Thanks @DaveE. I really appreciate your help.

@DaveE really thanks. It's much clearer to me now. Without the resistance of the earth, is the following reasoning correct? Let's assume a 12V battery. While the capacitor is charging, in the capacitor let's assume a drop of 10V, then I can have a difference of 1V (12V - 11V) between the...

@Gavran thanks. I had a hard time understanding that while the capacitor is charging the negative terminal and the negative plate are not at the same potential. I think this happens because the potential drop over a discharged capacitor is 0V, so there cannot be the same potential between the...

To be more graphic:

Thanks for the reply. I'm ashamed that I still don't understand. We start from the initial situation with the plates discharged, when the cables are connected to the terminals (this means positive terminal to a plate, negative terminal to ground, and the remaining plate to ground), why do...

I'm reading the capacity chapter of Serway's book, and I had a question about the charging of a parallel plate capacitor. Let's assume the following situation with a modification of the circuit in the figure: we connect the negative terminal of the battery and one of the capacitor plates to...
