Current in metal rod of gold leaf electroscope -- is it there?

[gracy]

In gold leaf electroscope
from the following video I have a doubt

From time 2:11 to 2:14 flow of negative charge i.e flow of electron won't it cause current?

Simple rule, which always applies. If charges move from A to B then a current flows.
Of course, once the charges have stabilised on the electroscope, no more current will flow. (I = dQ/dt)

once the charges have stabilised on the electroscope

Means ?When ?once the flow of negative charge i.e flow of electron is stopped.

Well, isn't that the definition of an electric current?
If no charge is flowing from place to place, is there any current?

No.

So that is your answer. Once the charges have all spread out to the minimum energy configuration (in nanoseconds) the current has stopped.
