Four questions about (Super) capacitors in series

Actually, that's demonstrably not true on both a cognitive and neuro-biological basis. Take Autism and Alzheimers, for example; both show divergence in cognitive function and neural anatomy.
People really do think differently, and the people who think differently have brains that are physically different. There are also intrinsic limitations in learning because of this.
I have to apply myself differently to learn something than you might. Both the method I use to learn, and how I learn to use what I've learned are different. This comes up in math education, for example, where there are at least five different ways to do division. All of them yield the correct answer. But not everyone grasps each different version equally easily or can do them equally well. Some people get stumped if they're taught one way and assume "I'm no good at math" until someone shows them a different way.
I knew someone who was about to fail out of school before I went around the room with her measuring things and moving fingers left or right. After that she was able to do arithmetic; negative numbers suddenly made sense! She went on to become a teacher. I also knew someone who was a slacker art major until a professor challenged him to learn calculus. So he spent one month stoned the whole time doing nothing else but learning calculus. When I last saw him, he was doing six body gravitation problems.
People are really weird, but really wonderful when their weirdness gets channeled in productive directions.
I'm finding that learning components individually does me no good. I have to think about an entire circuit, and all the aspects of it (capacitance, inductance, resistance, vibration, and temperature) simultaneously to make sense of it.

Interesting: I've always kept my caps at 2.2V or below.
I've also noticed that if I apply a pulse to them that it starts a wave of voltage changes (where the wave is the rate of change and direction). The wave has ripples, and it looks like a standing wave in some ways. I assume there are multiple effects going on simultaneously, and I'm guessing that different caps would have different frequency responses and Q's in response to a pulse too.
Not the ideal way to start learning about capacitors when they behave so differently from a textbook!

Those are disorders. Obviously disorders do not count in the categorization of normally functioning brains.

I'm sorry, but unless you wish to claim you have a brain or learning disorder, I'm not buying it.

But this is wrong. When we learn math we do not learn ways to do division, we learn what division is. Once we understand what division is, we see that all ways to do division are somewhat equivalent, and we become able to invent our own ways of doing division.

If you wish a different perspective, search on "fmri learning". For example : http://drexel.edu/now/archive/2018/May/New-parts-of-the-brain-become-active-after-students-learn-physics/
Even "ordinary" people exhibit highly divergent neural pathways.
Consider this too: https://www.scientificamerican.com/article/scientists-surprised-to-find-no-two-neurons-are-genetically-alike/
Another example, for which I can't find my bookmark: After years of performing hundreds of human dissections, a anatomist noted that he had never seen a single body with the textbook number and location of lobes in the lungs. Textbooks present an average, but like the average family with 2.5 children, it doesn't exist in real life.

--- Quote from: havewattwilltravel on August 23, 2018, 11:33:56 pm ---Is the resistance in the middle is impeding the current flow in the outer capacitors as much as it is impeding the flow in the middle one then? For an electrostatic potential to form, the electrons have to move (assuming a shift in probabilistic charge distribution is movement), so anything that impedes their movement will impede the potential from forming anywhere in the circuit equally?

For example, here you have strung a lot of complicated words together in a jumbled way that conveys almost no meaning. It's like you have got some words out of the dictionary and put them in a blender. This makes your question impossible to answer because it isn't a question.
It seems you have not yet formed an understanding of the most basic ideas of electricity, yet if that is the case where did you come across such complicated words?
