TSny reacted to vela's post in the thread LC oscillations - two capacitors and an inductor with
Like.
To fill in a step that wasn't immediately clear to me in the solution in post #3: when the current ##i## is at a maximum, the voltage... -
TSny replied to the thread LC oscillations - two capacitors and an inductor.But I think it's interesting to determine the polarity of the 4 plates at the instant when the current first reaches a maximum (assuming...

TSny replied to the thread LC oscillations - two capacitors and an inductor.I think this is OK. I’m not sure of your sign conventions for the charges on the capacitors. For example, does your charge ##q##...

Are you sure both capacitors are discharged completely when the current through the inductor is at a maximum? That’s true in the case...

TSny replied to the thread LC oscillations - two capacitors and an inductor.Yes. Good.

TSny replied to the thread LC oscillations - two capacitors and an inductor.Consider the section colored blue. This is a single piece of conductor. What is the initial total charge on this piece? Does the...

TSny replied to the thread B Feynman QED Questions.Consider, for example, the arrows corresponding to reflections from C and G in Figure 24. Feynman is saying that the lengths of these...

$$\frac{1-\delta}{[2(1-\delta)]^{\frac{3}{2}}} = \frac{1}{2^{\frac{3}{2}}} (1-\delta)^{-\frac{1}{2}} \approx \frac{1}{2^{\frac{3}{2}}}...

TSny replied to the thread 5 charges within a square boundary.Since the numerator of ##F_{right}## has a factor ##(1-\delta)##, it will be easier to first simplify ##\dfrac{1-\delta}...

TSny replied to the thread 5 charges within a square boundary.The right-hand is not a correct first-order approximation to the left-hand side. The expression ##2-2\delta + \delta^2## can be...
