It is a light hearted joke that connecting a power strip to itself is a source of "infinite power". While this is obviously untrue, I always disregarded it and never really thought much of it, because I thought the reason was seemingly obvious. However, after actually thinking about it, I had a few doubts on what exactly would happen when you made such a connection.
My intial presumptions were that there would be no current because there was no source of emf, and such a connection would never cause a flow of charges becuase there will be no electric potential difference between the two pins of the socket. I think this is right, but please correct me if I am wrong.
On looking it up online, I found some sources suggest that the "remaining current" would "drain" away almost instantaneously. Other related terms were "charge stored in the wire" and "sapped by the resistance of the wire". This is causing a lot of confusion. All the terms in quotes are in my opinion, a poor choice of words and are really unclear to me.
The only close analogue I could come up with was an RC Circuit, that was discharging. This would justify the instantaneous draining of charge, and the build up of internal energy in the resistor (which I think are the meaning of those phrases). However, a discharging RC circuit in itself contains idealized wires and a parallel plate capacitor in series with a resistance. Imagining such a combination of elements in a single wire is actually confusing me a lot, and I cannot wrap my head around it.
If this is the correct analogy, could someone help me understand how a wire could act as a capacitor and a resistance simultaneously? If not, could you tell me how this instantaneous discharge occurs?
Any help would be appreciated!
