Re: [Fwd: Re: capacitors don't store charge]

Ohh let me get one in there :

Think of caps as a large piece of rubber.  If you push on one side of them,
it bends,
pushing out on the other side, but only to a point.  When the pressure is
gone, it
will bend back, causing a + pressure on the "pushed" side to have some
