3) I?m not sure how to explain your example of two open relay
contacts in series, since the isolation material (air) is presumably
the same in both relays. However, when the two materials differ in
composition, there can be unequal division of the surge voltage as John
Woodgate has explained.
The supports for the relay contacts can have different insulation
resistances, and maybe capacitance but that would normally be very
small.
