Thanks :)

Actually one more question; what would be the final potential inside each resistor in a realistic and ideal circuit? Are they just at the same potential as the connecting wire?

You're a champion, thanks for your help :)

Thank you, I managed to get the right answer with that help. Physically, what happens in terms of the resistors at the open terminals + and - of v0 once the current is turned on? I imagine that initially (for a brief amount of time) we have current flowing one-way into both open terminals...

Homework Statement http://i.imgur.com/ij4eHqM.png?1?5000 Homework Equations KVL, KCL, Ohm's Law, I guess The Attempt at a Solution Tried node analysis but I get 4 equations in 5 variables, so no specific solution. I don't think the circuit can be simplified either. A friend...

Thanks, after emailing the TA he confirmed that indeed fo is arbitrary here, and so fo = 2fc is the way to start answering this.

Homework Statement http://i.imgur.com/01AUp.png Homework Equations The Attempt at a Solution Having some problems with this question, using a third + first order nonlinear device to make a multiplier. I'm fine with using a second order, but this one is stumping me. So, I...

Because doing hard, abstract problems creates the neutral networks that allow you to do hard, abstract problems. Even if you never have to do that problem again, the next time you come across something vaguely similar, your brain will say, oh that looks familiar... here's the thought processes I...

http://en.m.wikipedia.org/wiki/Planck's_law

Planck saw the introduction of the constant as nothing more than a mathematical trick that reproduced the experimentally observed spectra; he didn't believe that it represented anything physically. Einstein realized it was more than just a mathematical trick, it represented an actual physical...

Awesome, thanks for the replies!

All three seem to be loved, mathematically rigorous, and appropriate as undergraduate-level texts. I have a good knowledge of classical physics, ODEs and PDEs, linear algebra and multivar calculus, but no knowledge of analytical mechanics or QM. Some opinions on these or other recommendations...

Awesome, thanks. I did try to set up the integral first and it quickly turned into a cluster**** haha

Homework Statement A very long cylinder has charge density L/m and radius a. Find the electric field at a distance r, with r > a. The Attempt at a Solution I construct a gaussian cylinder around it with radius r, and then from Gauss' law the field at any point on it's side surface is E=...

Hi, I have a B.sc with first class honours, with a major in biochemistry and I want to do a phd in astrophysics. I have two years of undergrad physics and a good knowledge of vector calculus, DEs, linear algebra, etc. What are my chances of getting into a program? I know in america you guys have...
