Quick question about RC circuits

  1. Jun 3, 2007 #1
    While working on an example in my Circuit Analysis textbook, I came upon the following circuit: A 9v battery is connected to a resistor R1 (this is the left loop of the circuit). It is also connected to a resistor R2 and a capacitor C1 that are in series (that is the right loop). The authors are claiming that no current flows through R1 and C1. Is that true? aren't we suppose to see a current flowing through both loops according to Ohm's law?

    is this the circuit?

    oh never mind I just remembered that DC voltage supplies produce zero currents through capacitors

    after the time constant yes, but initially there is a current
