Oomis, your part about electricity constantly running in wires is interesting. I am not sure how the following would affect the halacha, but when the switch is off, there is a voltage, but no current. When you turn the switch on, or chas vshalom stick any conductor or even part of the body (since it conducts to some degree) into an outlet, you are creating a current. It is like water in a faucet which when the faucet is off, there is pressure behind it but no flow. When you open the faucet, the pressure forces the water out, and a stream flows. If electricity depends on voltage, then it could be as you say. However, if it depends on creating a current, then would be different.
