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?
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...

My textbook (Churchill) is asking me to prove that the contours $$u(x,y) = c_1$$ and $$v(x, y) = c_2$$ where $$u$$ and $$v$$ are the real and imaginary components of an analytic function $$f(z)$$ are orthogonal at any point by noting that $$u_x + u_y \frac{dy}{dx} = 0 $$ and...

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...
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...
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...
