This page http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capeng2.html talks about how the battery does work to move a charge from one plate to the other plate. Can charge jump across the gap between the plates? I was under the impression that the plates get charged due to electrons traveling towards/away from the plates via the wires which are connected to the battery and not due to electrons jumping between the plates. Thanks for your help!!
