physics of capacitors and inductors...can u help

[azaz104]

consider this question....

i need to know the real physics on how a capacitor works, not just simple talk, i need some physical and mathematical interpretation of a capacitor and how it physically charges and where is the energy...i know it does not Store energy..since it does preserve the change in potential, but how....

the same thing goes for inductors.

what you mean by it does not store energy? i always thought that capacitors and inductors save energy; the one is in electric field 0.5*C*V^2 and the other in the magnetic field 0.5*L*I^2;
maybe i understand wrong what you mean

i didn't mean store energy..sorry..i meant charging..cause capacitors don't charge

Hi, i don't know what you want, but take a look at this book for an introduction on
capacitors and inductors

JR Reitz and FJ Milford, FOUNDATIONS OF ELECTROMAGNETIC THEORY.

If you want to know how the equations are obtained (ie cv = q and v = ldi/dt), for ex the eq of capacitor, it comes from thinking of two conductors charged with q and -q at a distance d, then find the difference in potential between them (which is a function of q ie constant X q)

You need Eddie P.

Check out Edward M. Purcell's classic text: Electricity & Magnetism

Get it, Read it, Love it.

i made a search on google and edaboard but found it to be only in bookshops...i'll try to search the library for it, but i'd appreciate it if i can find it as an ebook.

i would recommend the feynman lectures(vol 2) for u.right from the basic equations to the actual charging process,which involves changes in both electric and magnetic fields and its description using bessel functions,u will find everything.u would also find it easily in any good library.

I would like to suggest you to read 'Fundamentals of physics, written by Halliday & Resnick'. This textbook is an excellent book which is suitable for all freshmen to read.
