I could imagine it is not very descriptive, sorry. I found a link with a similar setup. The only difference is that there is a surface charge density \rho_{s,c} in between the dielectrics at radius c (Nothing else is known of the boundary at radius c)...
Hello. I have DC going through a coaxial cable, and I have calculated the E fields of the two dielectrics in between to be E_1 and E_2 with help of their D-vectors. The dielectrics are cylindrically shaped like the conductors. As in, one is in contact with the inner conductor, and one is in...
Thank you very much! What I have looked through so far seems very well explained. Now I also know which classes to take later this year, haha. I think with all of these supplementary suggestions, it can't go too wrong.
Hello, and thank you both for the suggestions. I will definitely keep the online book in mind. I am not going to buy another book, though (Class reference books are enough to empty most student pockets, including mine!), but I know the book by D. Griffith from other students in my university...
Hello. I am currently reading on electromagnetism in university. However, I feel that I sometimes get lost in the the math in an otherwise excellent book (Field and Wave Electromagnetics by David K. Cheng), so I would like to ask, if somebody knows a good, steady resource for understanding the...
The abandoned city itself is very fascinating, I think. The city is pretty much untouched (Except by looters) and it looks like an old soviet city. As far as I know, it's not that hard to gain permission to the city. But I am not so sure about the zone of alienation. But I doubt entrance to the...
Thank you for the simple answer :-) But if you get a whip over your fingers, for instance, it will feel warm (And quite painful aswell) for quite some time. Is this affecting the random movement of the molecules then, or is it just a "response" from your body?
Now, I am very dull, but something that has made me ponder for quite some time is movement and how you define it. As I've understood the movement of the atoms is what can make an object feel cold or warm or maybe even painful, and when you drop an icecube in a cup of water it will cool down...
Hello. I've been on this forum for a while. Though I never really bothered clicking the "register" button until now.
I am no scientist (In fact I still haven't reached university yet), so this might be a bit, well, simple-minded.
Recently I've had some thoughts and discussions with my friends...
