I am having a lot of trouble understanding the idea, usage, and implications of capacitance. I know what a capacitor is and what it does, but the whole realm of transistor/parasitic capacitances, and interconnect capacitances is so mysterious to me. I don't really know those capacitances are there (and why they aren't somewhere else). I don't know which capacitance exists but has been ignored (deemed insignificant), and I don't know whether a capacitance I expect to exist actually exists at all.
A very rudimentary approach I take is to use the idea of opposite charges attracting each other. So whereever you have current, there is charge, and that charge is attracting other charge (be it on a wire, gnd, or semiconductor device).. so basically you have a capacitance to each and every other electrical object.
Could somebody please point me to a book or resource where the whole nature of capacitance is dealt in detail?
