say we have a unit +4v N 0v- If you measure the potential on the N plate it will read 2v in relation to the - plate and -2v in relation to the + plate. The side facing the 0 plate will act as an anode to the -0 plate and the side facing the + will act as a cathode to the +4v plate.
The same applies right across any number of neutral plates.
