My wording was very poor. It was not the intended meaning. (But I hope the intended meaning was clear from the latter part of the post.)...

I may misunderstand the issue you are indigating. But to try to answer your question... Take three conducting plates (equal sizes...

Well, I'm not sure if this answers your question but here’s a qualitative (definitely not rigorous) attempt... Thinking visually, a...

@tellmesomething, this might resolve specific issues you raised…. ‘Ground’ and ‘infinity’ are not necessarily equivalent. I believe...

Thank you all for explanations. I tried to prove this to myself by contradiction, but it might be an oversimplification. If we assume...

Hi @tellmesomething. I understand what you mean - sorry for not picking it up sooner. I’ve edited what I said in Post #8 as it may be...

The initial net charge is non-zero. But when plate-3 is grounded, charge will flow between the system and ground. The final net charge...

The Post #1 diagram is misleading. It would be better to include an open switch in the earthwire and ask something like: "What are the...

I don’t think that’s correct – there will be discontinuities in charge-densities and field-strengths as you move left to right. To add...

I think you are right. The book solution implicitly assumes that the voltage at the bottom of slab 1 is constant across the width, which...

FWIW, on the right-hand side you are adding quantities with different dimensions: ##v## has dimensions ##LT^{-1}##, ## \frac {dv}{dt}##...

@NTesla, maybe this is one source of your difficulty... That's not entirely correct. The horizontal section of the chain is...

Do you mean the equations from your Post #1? I can see them. Here's a copy, though LaTeX rendering may be a problem:

Yes, that's a valid point.

@NTesla, the last part of the question on the screenshot is missing. So here’s what (I believe) it should say: "... At a certain...
