RC & LR time constants

  1. Apr 4, 2009 #1
    How does the relative position(series or parallel) of a resistor affect the calculation of the RC and LC time constants. In other words is a RC time constant still R[tex]\times[/tex]C requardless of whether or not R and C are parallel or if R and C are in series. Same question with LC time constants, is it [tex]L/R[/tex] whether or not L and R are in series or parallel to each other. Thats how it looks in my text book when they derive the time constant, it does seem conterintuitive to me though.

    Thanks a lot.
