I have a range of results from scanning a piece of metal of length L. The results from the scan are %FSH of the oscilloscope. I have to analyse the noise of the signal and thought I'd do this using a fourier transform. Using the range of results as follows could you please tell me...
Hi I was wondering if you can help me.
How is the concept of the displacement current used to resolve the ploblems with the application of Ampere's law.
I know that the modified ampere's law is
I just know how the displacement current jd is used to solve the...
The question stated is a question on a past exam paper, I am trying to review these questions.
I need to derive the boundary counditions satified by D at the interface between 2 media
I was wondering if anyone would be willing and able to help me with this question.
Q. Derive the boundary condition satisfied by D at the interface between 2 media.
I know that the D field is continuous at the suface, but I need to be able to derive this.
If anyone can...
I don't fully understand, do i have to use maxwells equations to find the charge density, and if so how does this apply to a dielectric between 2 capacitor plates. I thought that the E field would be E(0)/EPSILON(r) where E(0) is the Electric field of the capacitors without the dielectric...
Electric energy of a dielectric sphere!!
Hi there, I have attempted a question, I was just seeing if some one can go over it and check if it is ok!!
Q. The Electric field E inside a dielectric sphere placed between the plates of a large parallel-plate capacitor is uniform. Given that the...
A good way to understand this is probably to read up about the wave/partical duality. This should be applicable for all text books.
Like TD said, radiation, behaves like waves and particles. Its a parradox that is very important in modern physics. Its not much help but its something tht needs...
Total energy of a dielectric sphere please help!!!!
I have a problem that I can not do after searching the net and looking through my notes and text book. I think it is a basic electomagnetic field question but i just cant get my head around it.
The question is:
The electric field E...
