Capacitor with unequal charges on the plates
Suppose we have two plates which have unequal magnitudes of charge. In order for the two plates of a parallel plate capacitor to have significant unequal magnitudes of charge, it would have been necessary to charge them separately by some external means before bringing them together to form a capacitor. - Download [PDF]

How do we know that both plates of a capacitor have the same charge?
Maybe the two plates of capacitor have unequal charges. The excess goes to battery somehow. Jun 24, 2023 #5 Kashmir. 468 74. PeroK said: Do you have a particular set-up in mind? In general, if the total charge on a system is zero, then the positively charged components must have equal and opposite charge in total to the negatively charged ...
How do capacitor plates maintain equal but opposite charges in a …
$begingroup$ @dts If you have two sheets of unequal charge, then the fields outside those sheets will no longer exactly cancel. You only get zero field outside the capacitor if there are equal and opposite charges on the plates. ... +Q_text{bottom}$ superimposed on a parallel-plate capacitor with charges $pm(Q_text{top}-Q_text{bottom})/2 ...

$begingroup$ But suppose we have unequal charges on the plates say Q and 0. Then why don''t I end up with charges -Q and +Q on the other plate and instead have -Q/2 and +Q/2? ... Typically parallel plate capacitors are idealized somewhat. The field between them is considered uniform. Normally this is a very good approximation. But it is ...

Solved Charge build up between the plates of a capacitor
Question: Charge build up between the plates of a capacitor stops when? A) Charge on both plate is the same B) There is not a net charge on the plate C) unequal amounts of charges accumulate on the D) The Potential difference between the plate equal the potential difference between the eternal of the battery What happens when a rubber rod is rubbed with a piece
Charge on plates of two capacitors in series are not equal
So Q₁ is the total charge on C₁. Q₂ is the total charge on C₂. This charge will be due to any initial charge ( Q₁(0) = V₀₁·C₁, Q₂(0) = V₀₂·C₂ ), and the charge flowing through the capacitors because of the switch, which we can call Q.

$begingroup$ @garyp - no, the force of attraction of the charges of one plate on charges in the other plate rapidly fall off when you move away from the area of overlap. The approximation will only break down if the ratio of spacing to lateral dimension is not small (that is, when the gap is "large "compared to the size of the plate) - in that case edge effects are not insignificant (but …
Capacitance of capacitor with unevenly charged plates
In summary, the question is about finding the capacitance of a parallel plate capacitor with unequal charges on the plates. After discussing various scenarios, it is determined that the outermost surfaces of the plates will have equal charges and the innermost surfaces will have opposite charges. This is based on Gauss Law and the fact that the ...
How does charge redistribute in a capacitor?
But for there to be unequal charge on two capacitor plates there needs to be a difference in the plate areas and, this creates "fringing" to a third party (usually ground) like this: - The overlap area between left plate and …

How do I find the energy stored in a capacitor that has unequal charges
But, in normal capacitors forces are working to keep the charges on plates, while here forces are working to keep the charges away from plates. This is because in normal capacitor forces are attractive, while here forces are repulsive. So, result is- in normal capacitors excess charges in wire can be ignored, but here it can''t be ignored ...

Why do both plates of a capacitor have the same charge?
I see it like this. When plates have unequal charge, there is nothing to keep the extra charge of the higher charged plate on it. The extra charged particles will just repel each other and find their way away from the plate (it is a conductor, after all).

Charge On parallel plate capacitor?
If the plates of a capacitor have unequal charge, there is now energy stored in more than one capacitance. There is the capacitance that exists between the two plates (the mutual capacitance) as well as the capacitance of each plate to the environment.

$begingroup$ The total energy stored in an electric field goes roughly like the volume where the field is strong. A capacitor whose plates have equal charge has a strong field in the gap between the plates, but a capacitor whose plates have unequal charge has a "fringe field" which is non-negligible outside of the capacitor.
