    i cant understand how they got the praph of the capacitator

    i clearly see that as the frequency goes up so does omega so the denominator goes up
    and the whole expression decrisses

    why does the gpath goes up as the frquency goes up

    It looks like they have got the VR and VC labels wrong.

    The reactance of a capacitor drops with rising frequency, so the voltage across the capacitor would drop too, in a series RC circuit.

    Was this in a book?
