Figuring physics:SHOCKING TALE

摘要

On his lab table, Jack plays with a simple circuit that consists of a 70-V source in series with a 2000-Qresistor, and an open space between two terminals, A and B, across which is a potential difference (PO) of Vi. With a body resistance of 5000 Q across his hands, Jack simultaneously touches terminals A and B with his hands, which results in a Pb of V_2 across terminals A and B.
