Initial conditions question

  1. Jan 19, 2010 #1

    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?
