MH's ideal coil and voltage question

[Johan_1955]

That almost sounds like TK lol.

Hole D-base with different Cookie's remarks collected!

What do you think about:

Always, Independent 3e party validation, all less is don't pay attention, except for: Nasa, Mit, Lewin sometimes, .............

Sweet dreams, and go to bed!

This would more so describe an ideal inductor that also has an infinite amount of inductance.  As such, when connected across a voltage source, no current would ever flow as the time constant would also be infinite.

The time constant is infinite.
Tau=L/R. There is no R,as it's an ideal inductor.
Tau=L/0 = infinity.

the ball, shopping cart, whatever.. floats through the perfect vacuum unimpeded. ok.

well how do we know this if there is absolutely nothing else in this vacuum to compare
its relative motion to. the presence of something else, anything else, could
be considered a resistance. a way to set a Tau. For all intents and purposes, it's at rest.
To say otherwise would be to simply assume it in test parameters. Newtonian Physics
really don't much belong in quantum mechanics anyhow do they? This seems more of
a time paradox. I understand I provide nothing to the convo without being able
to at least properly explain it, but maybe possibly someone else can see where I'm coming
from here. The 'ground' as Webby put it imo seems like light speed. Resistance is what keeps
our energy from traveling at light speed right? Whether, electric current, or whatever?

Tau has no bearing on whether current can/will flow or not. The effect it has is how "curvy" the rise of current is, relative to the timing of your test. With an infinite tau, the curve is going to be a straight line, not only because the time is infinite, but also because the beginning part of the curve is almost straight anyway.

Electrons move at the speed of light even through resistors as far as I know.
