Series connection of capacitors
This C divider ratio will have an intermediate V depending on the ratio of C1/(C1+C2) across C2 of the difference V.

So the smallest C value has the highest V and then leakage R ratio’s will affect the steady state V after some time constant T=(Rp1+Rp2)*C1//C2 to 64% Delta V @ 1T

This “Capacitive Transformer” method is a common method for sampling a single phase HVAC , not shown here, to a safe LV for sensing using Vb with V2 =0V or grounded.     

e.g. a bushing 100 pF 100kV cap (arc protected) integrated in porcelain, to a 10uF cap to get 1V ,  used by ABB.

Can you think of any practical use for this in a switching S&amp;H  circuit? For DC and small signals? Can you imagine any effects in switching cascaded FET’s at high speed with a large Ciss load from a smaller Coss driver with higher RdsOn?
