I have been looking at the information contained in the text book section on this website on electrical safety, which has been really useful and informative. However, I now have a question that I've not been able to find the answer to by simply google searching - perhaps because the answer is really obvious!
On this page http://www.allaboutcircuits.com/vol_1/chpt_3/3.html it shows a diagram with an explanation that a circuit that isn't grounded will not cause an electric shock if a person (or bird!) were to touch it (provided no ground fault).
From further research, I believe that an airplane's electronics are grounded, whilst in flight, by a connection to the metallic body of the aircraft. I am assuming the people in the airplane are not earthed - to 'Earth' or to the metallic body of the aircraft as they would be insulated from the metallic body of the aircraft.
So, my question is, if people inside they aircraft are indeed insulated from the ground of the aircraft, would it be possible to receive an electric shock from the aircraft electronics, from say exposed wires? My instinct is that yes, of course there would be a shock! However, referring back to the previous link, if there is no complete circuit from the exposed wires in the electronics to the ground through the person then an electric shock would not be received.
Any help would by appreciated.
