Thank you, I think I got it. If I have any vector field ##\vec v=\vec v(x,y,z)##, then in general the componentes would be ##v_x... -
Dale reacted to ergospherical's post in the thread I How to picture the vector potential? with
Like.
Yes, in the general case ##\mathbf{A} = \mathbf{A}(x,y,z,t)## is some vector field that depends on position (and time), and you'll need... -
The radiation resistance is supposed to be very small and does not change the logic in a fundamental way. The time constant (TC) does...
-
Thanks Dale for the info. So, this resistance would be a factor in the ramp up of voltage to V. If the ramp up is done very slowly, then...
-
Thanks for making my point! Yes, “hours” is not forever! However, the analysis says times required are likely to be much longer than...
-
Dale replied to the thread I Paradox of Superconductivity.Agreed. You could design circuits with a superconducting component and a long time constant and you could design circuits with a...
-
Dale replied to the thread I Paradox of Superconductivity.What analysis? All I have seen is your unfounded assertions to that effect. Indeed. Please do.
-
The physical arrangement of the circuit components will be important. You have not described the complete circuit. Depending on the...
-
You keep pointing to contrary "observations". To support that claim, please cite a scholarly reference that exhibits what is observed...
-
Dale replied to the thread I Paradox of Superconductivity.Ramping up a MRI magnet is almost linear, it takes a few hours which is not almost forever, and I don’t see what you think is contrary...
-
Dale replied to the thread I Paradox of Superconductivity.This depends on the geometry but is typically in the range of 50 to 300 ohms.
-
Dale replied to the thread I Paradox of Superconductivity.Hmmm. What makes you think that? Do you have a reference that shows an experiment where it doesn’t match?
-
The series R+L will need a return circuit, that has not yet been defined. In effect, R1+L1 is a transmission line operating against an...
-
Dale replied to the thread I Paradox of Superconductivity.As @renormalize mentioned, you have arbitrarily high frequencies for switching on an ideal source.
-
Are you sure? The idealized version of "the power is turned on" is a step-function in time, which contains Fourier components with...
