Undergrad Paradox of Superconductivity
Thanks for making my point! Yes, “hours” is not forever! However, the analysis says times required are likely to be much longer than that. I am calling it a “paradox” and NOT a contradiction. I believe there is an explanation, but the discussion here has not yet yielded the resolution! Following...- Karmyogi01

Undergrad Paradox of Superconductivity
That's not what I said. Please read the whole post. Your first paragraph states the obvious!- Karmyogi01

Undergrad Paradox of Superconductivity
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 the impact of the radiation resistance can be made insignificant. The real story begins after reaching the desired very small voltage V. From here on, the...- Karmyogi01

Undergrad Paradox of Superconductivity
As stated above, I mentioned "ideal source" for the sake of clarity only and mentioned already that we do not necessarily have to assume that. I stated this already. To answer your question regarding TC, please tell me your estimate of "radiation resistance."- Karmyogi01

Undergrad Paradox of Superconductivity
The radiation resistance is supposed to be very small and does not change the logic in a fundamental way. The time constant (TC) does not match what we observe. In addition, the question is not constrained to only an ideal power source.- Karmyogi01

Undergrad Paradox of Superconductivity
I am assuming an ideal power source with zero impedance for clarity. However, the fundamental logic will not change even if it were not an ideal power source.- Karmyogi01

Undergrad Paradox of Superconductivity
There is no resistor in series. All components are superconductive. R is vanishingly small- Karmyogi01

Undergrad Paradox of Superconductivity
For a series R-L circuit that uses superconductive components, how long would it take for current to build up after the power is turned on?- Karmyogi01

Graduate Charge to mass ratio of a photon
I truly appreciate you trying to shed very helpful light on the subject. Let us consider a situation wherein a blackhole gobbles up a large amount of charged mass nearby when emission of radiation was in progress from a source outside its blackhole boundary but quite close to it. It results in...- Karmyogi01

Graduate Charge to mass ratio of a photon
Thanks. Interaction of a particle, including a photon, with an electrogravitational field depends on its charge to mass ratio. If we do not know the charge to mass ratio (q/m) of a photon, then we cannot predict or understand its interactions with an electrogravitational field. If q/m for a...- Karmyogi01

Graduate Charge to mass ratio of a photon
Photon is supposed to have a vanishingly small amount of charge and a vanishingly small amount of mass. However, I have been unable to find any information regarding photon’s charge to mass ratio (q/m). I will appreciate any insight on this issue.- Karmyogi01

Graduate Understanding the Gravitational Redshift Caused by a Black Hole
Thanks for all the very helpful insights provided here! I truly appreciate it! So, if this expression for the redshift is not valid for this region under the blackhole boundary, which one is the right expression? Let us consider a scenario wherein the mass of the blackhole increases, when...- Karmyogi01
