 Charged Capacitor At http://en.wikipedia.org/wiki/Capacitor  and http://en.wikipedia.org/wiki/File:Capacitor_schematic_with_dielectric.svg  , a diagram shows the classic picture of a charged capacitor. It has +Q charge on one plate, -Q charge on the other plate, and a uniform electric field E between them.   http://www.tpub.com/neets/book2/3b.htm , Google Hit no. 2 out of 36,000 says; “At the instant the switch is thrown to position 2 (fig. 3-6(B)), a displacement of electrons occurs simultaneously in all parts of the circuit.”  “At the instant the switch is closed, the positive terminal of the battery extracts an electron from the bottom conductor. The negative terminal of the battery forces an electron into the top conductor. At this same instant an electron is forced into the top plate of the capacitor and another is pulled from the bottom plate. Thus, in every part of the circuit a clockwise DISPLACEMENT of electrons occurs simultaneously.” Since there is distance between battery and capacitor, it is wrongly asserted that there is instantaneous action at a distance. This contrasts with http://www.ivorcatt.co.uk/cattq.htm , where a voltage/current step advances at the speed of light from battery to capacitor guided by the two conductors. The start-up for the battery is not “At this same instant” as the start for the capacitor. If the distance down the wires between battery and capacitor is one foot, the delay is one nanosecond.   Ivor Catt. January 2010   .
