When we are negatively charged, and we touch a doorknob for example, why does the shock happen (i.e. the flow of charge)?
I understand that the electrons want to flow to positive charges, and I know that as I approach the doorknob, it gets polarized and the positive charge is closer to my hand.
But what I don't understand is what happens next: where do the electrons go? Why would they want to flow to an object which has net charge zero?
After I touch the doorknob, and the electrons flow (why? No net charge) would the doorknob now become charged and I would become neutral again?
