Why Is the Voltage on Both Capacitors 12 Volts in This Circuit?

why in this circuit they say that in t<0
the voltage on both capacitators is 12 volts??

if both points of each capacitators is connected to the voltage source directy
then 12 volts is ok.

but here we have a resistor between them
this resistor drops the original voltage
it cannot be 12

If there is no current through a resistor, what is the voltage drop?

The current through the resistors has decayed off to zero, if the circuit has been connected up like that for a long time before t=0. Make sense?
