Well I guess it would be something like this:
Not sure what Earth capacitance would be, infinity?. Resistance assumed to be 5 ohms.
Wire inductance values got from an online calculator (d 2mm, L 1m).
Because I know that according to circuit theory the current is considered to be near zero...
My goal is more or less to understand intuitively why there is only negligible current in the described scenario.
I'm not sure entirely what mental model ("reality") to use to wrap my head around it, as there are plenty and they are easy to intermix.
But so far to my basic understanding (please...
Incorrect, not sure why would one state that. I'm trying to learn.
Why is that so? Yet again reiterating my thought process - if there's a potential difference and earth has capacitance to receive and give charge, why is there only negligible current?
To my understanding during one cycle of the...
Thank you both for your answers.
I agree that the drawn circuit isn't the best and I mainly added it to try to help/visualize the question(s) at hand. It seems it adds more confusion than clarity, so let's try to approach this purely from a theoretical perspective first and move on from there...
I understand your answer(s) from a circuit theory point of view, but theoretically, shouldn't there be a current, even if it's negligible? I mean, how antennas would work if open circuits wouldn't have current?
Hi,
Let's say we have a basic AC generator, where a single wire is rotated within two magnets:
Due to the electromotive force, a voltage is generated so that Va - Vb = 120V.
Let's now ground Vb side directly to earth, while leaving Va still open:
We can say that Vb = Vc = 0V and Va...
