 Apr 14 comment How does the voltage across an inductor and a capacitor vary in series LCR circuit about resonance? I think if you include R then we wont get the infinities at \omega_0. Otherwise, it is consistent with my plots. Thanks. Apr 14 comment How does the voltage across an inductor and a capacitor vary in series LCR circuit about resonance? I have edited the question to include the details of what I've tried. Apr 14 comment How does the voltage across an inductor and a capacitor vary in series LCR circuit about resonance? Did you ignore R to simplify your calculations? I tried what you were doing but with R and I was thinking of plotting them using Mathematica beacuse I was having trouble doing it analytically. And I was working with the magnitude of the phasors. Apr 14 comment How does the voltage across an inductor and a capacitor vary in series LCR circuit about resonance? This doesn't answer the question. Mar 2 comment Have they really photographed light behaving both as a particle and a wave? Yes, that is consistent with what I have read. Feb 23 comment What are some open problems in classical electrodynamics? @Qmechamic, I am more interested in what hft describes as "clever little problems based on basic material". I am not looking for a discussion on "problems" that are resolved by the corresponding quantum theory. That is why I mentioned "side problems". Dec 15 comment What is the purpose of the factor $N/L$ in the magnetic field of a solenoid? Take a look at this question. It will clear your doubt physics.stackexchange.com/questions/113232/… Dec 14 comment How to calculate the value of gravitational acceleration of my town Both the formulas hold for different situations. I am thinking out loud here but I think what if we applied the latitude formula first to find the effective $g$ at that point and them used that value of $g$ as $g_0$ in the altitude formula, we might get a more precise value of g at the town which takes both factors into account? I am having doubts because as Qmechanic pointed out in the comment that the assumption that the earth is spherically symmetric (as we did in deriving the altitude formula) is inconsistent with the fact that earth is spinning. Dec 14 comment How to calculate the value of gravitational acceleration of my town Well, I plugged in the numbers into both formulas. And the 'altitude formula' gives a value of $9.79m/s^2$ and the 'latitude formula' gives $9.77m/s^2$. (I stand corrected, both of them give nearly equal values) Dec 2 comment How does this “simple” electric train work? Thank you for the explanation. Is the Lorentz's Force law F=q(vXB) the main equation behind this? Oct 19 comment Resources to learn about the Higgs theory at undergraduate level This paper has exactly what you're looking for: arxiv.org/abs/1207.2146 (Unveiling the Higgs mechanism to students by Giovanni Organtini) Jul 30 comment Fringe Pattern Brightness for Young's Double-slit experiment To explain the theta dependence you have to derive the diffraction integral which requires calculus. Jul 30 comment Fringe Pattern Brightness for Young's Double-slit experiment The brightness will be equal if you consider the effect of interference only. But the brightness will fall off if take into account the phenomena diffraction along with interference. May 22 comment Principle of Caratheodory and The Second Law of Thermodynamics I would definitely look it up. Thank you. This discussion has been very helpful. May 22 comment Principle of Caratheodory and The Second Law of Thermodynamics I still can't see how the concept of increase of entropy comes out of this for an irreversible process. ( I'm getting the feeling that this works only for reversible processes ). May 22 comment Principle of Caratheodory and The Second Law of Thermodynamics Can you elaborate on point 2? How does this distinction exactly melt away? May 22 comment Physical motivation for differentiation under the integral Actually the examples from Quantum mechanics would show how neat (and essential) this trick is. May 22 comment What are some good resources for learning how to apply vectors in physics? See, what you are actually doing is taking the projection of the vector along the line joining a vertex to the center. Think along this line and you shall find the answer. May 22 comment What are some good resources for learning how to apply vectors in physics? It is a very simple problem. Think about the angle that B makes with the line joining the center and taking the cosine component May 22 comment What are some good resources for learning how to apply vectors in physics? You can post that specific problem here as a homework question and everyone can take a look.
