Why is capacitance a geometrical property?
We have seen since our school that capacitance is a geometrical property. It depends on the structure of the two electrodes. But why is it so. Can anyone shed some light on it?

Hi, I’m not sure I completely understand your question, but here are some thoughts. Capacitance is a measure of the amount of charge stored in a device, given the electrostatic potential. In the traditional example, a parallel plate capacitor, the amount of charge stored, and thus the capacitance, is directly proportional to the area of the plates. So changes in the geometry affect the area, which in turn changes the capacitance. I hope this is relevant to your question.

Capacitance is undeniably a geometrical property of electrical systems, and understanding this fundamental concept is crucial in the realm of electronics and electrical engineering. This intrinsic property arises from the geometry of the components involved, primarily the arrangement and separation of conductive plates in a capacitor. As described in detail at https://serviceteam.co.uk/cooker-hood-repair/, the geometric factors such as plate area and the distance between them play a pivotal role in determining capacitance. The larger the surface area and the narrower the gap between the plates, the higher the capacitance. This geometric relationship showcases how capacitance is intricately linked to the physical dimensions of the system, highlighting its status as a quintessential geometrical property in the world of electrical circuits.

It’s because the capacitance between two plates depends on the electric field between them, which is naturally geometry-dependent; you get a different electric field if you have charges in different places.
The dependence on electric field also explains why capacitance changes when you place a dielectric between the plates, because this also alters the electric field as is easily seen from Maxwell’s equations in matter.
Hope this helps, Tom

So here's the deal: capacitance between two plates is all about the electric field feeling. What's more, you know what's tricky? Geometry influences the shape of the electric field. Change the locations of the charges, and a new electric field appears. Isn't it amazing? Check out GradesFixer https://gradesfixer.com/ if you, like myself, need some clarification or new views on complicated issues. They feature a large amount of free writing samples that have been invaluable in my study. The way they break down topics makes them much easier to understand, especially when delving into difficult areas like Maxwell's equations. It's a goldmine for pupils trying to ace their understanding, believe me. Give it a shot and let the information flow!
