Like.
Assuming this is true (3- 5 yrs experience for an entry-level job is a non sequitur to me), how are any grads in your area acquiring the... -
vela replied to the thread LC oscillations - two capacitors and an inductor.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...

Consider the section colored blue. This is a single piece of conductor. What is the initial total charge on this piece? Does the...

vela replied to the thread LC oscillations - two capacitors and an inductor.Are you sure both capacitors are discharged completely when the current through the inductor is at a maximum? That’s true in the case...

vela replied to the thread Sequential measurements in quantum mechanics.You need to consider the properties of the eigenfunctions of a hermitian operator (section 3.3). ##\Psi## is the state vector of the...

vela replied to the thread Writing a vector parallel and normal to a unit vector ##\hat n##.Not at all. I meant what @kuruman explained above.

I can't speak for @vela, but the other line of reasoning I alluded to in post #13 is this. You want to write ##\mathbf A## as the sum...
