(If this is not the correct place to post this, can someone please let me know what is.)
In a Leyden jar, I have read that a charged object is brought in contact with the conductor in contact with the metal inside the jar, thus giving the inner metal a similar charge. And the metal outside the jar then gets an opposite charge.
For purposes of discussion, let's assume that the charged object is positive, so the metal inside the jar becomes positive and the metal outside the jar becomes negative.
My question is simply how does the metal outside the jar get the opposite charge, given that there is an insulator in-between?
I'm wondering if what is meant is not that the outside metal gets charge, but rather that polarization occurs within the outside metal, so that the inner surface of the outside metal becomes negative while the outer surface of the outside metal becomes positive, but the outside metal has no net charge?
At any rate, I'd be very grateful for an explanation of what is going on.
