I know that electrons flow across the wire from the source to the receiver, but would it be possible to keep these electrons on the wire after disconnecting the source and receiver?

If I have a charged wire and shape it into a spiral, is the electric field stronger?

What would these situations be?

I am sure many of you are familiar with the Impulse-Momentum Theorem: \Deltap = F * \Deltat Is there any way to mathematically derive the time that the two objects would stick together during the collision without using the left side of the equation?
