    people, i had this question in my head since years but never attempted to seek an answer until recently i saw a similar question in a MIT website.. Any thoughts?
    also, can we consider this as a form of storing energy?

    Electricity in the form of current flows from high potential to low potential. So when these two points are not connected i.e. nothing is plugged, electricity is maintained as potential difference.

    There will always be a difference in potential between the two points But NO CURRENT will flow between the points

    nothing happens, the electrons just waiting for a conducting medium to reach ground/other terminal

    It will be like no load condition of transformer, some energy is required to maintain potential difference.

    Practically, that's not correct. Primary winding of transformer doesn't have zero resistance. Hence, power is consumed by a transformer even if there is no load - the reason it's advised not to leave your charger( or any device using transformer) plugged into socket after charging is done.

    what i mean is even after
    consider primary winding resistance as 0, we need continuous supply of AC Input for maintaining potential difference.
