Talk:Body capacitance

Here is something I cannot understand about body capacitance: in a capacitor, there must be a positive side and a negative side. Electrons are put into one side of the capacitor and taken away from the other side. Why, with touch lamps and switches, can they detect body capacitance when only one piece of metal (one terminal) makes contact with the human body? Where is the other terminal to complete the circuit? The air?

Commercial capacitors always need two metal terminals, + and -. I need help understanding the full flow (complete circuit) of electrons, and it would help the article to illustrate where the + and - is.

I believe the human part of the circuit is both. X [Mac Davis] (SUPERDESK|Help me improve) 18:20, 24 October 2006 (UTC)
