    Engineering Solving Circuit Problems Using KVL, KCL, and Ohm's Law - Homework Help

    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?

    Engineering Solving Circuit Problems Using KVL, KCL, and Ohm's Law - Homework 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...

    Engineering Solving Circuit Problems Using KVL, KCL, and Ohm's Law - Homework Help

    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...

    Proof of orthogonality of harmonic conjugates

    Homework Statement 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...

    Signal Processing Help: 3rd + 1st Order Nonlinear Device Multiplier

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

    Signal Processing Help: 3rd + 1st Order Nonlinear Device Multiplier

    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...

    Maths in Engineering: Working on the Brain Teasers

    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...

    Exploring Planck's Hypothesis & Einstein's Extension to EMR

    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...

    Shankar, Ballentine or Zettili for a first book on QM?

    Awesome, thanks for the replies!

    Shankar, Ballentine or Zettili for a first book on QM?

    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...

    Finding the electric field of a uniformly charged cylinder using Gauss' law

    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=...
