Homework Help: Capacitor and reactance question

  1. Mar 6, 2014 #1
    A 9.08 microFarad capacitor is measured to have a reactance of 245.0 Ohm. At what frequency (in Hz) is it being driven?

    I converted 9.08microFaraad in farads- 9.08x10^-6
    THe formula i used was 1/(2*pi*f*9.08X10^-6) -- f = 17528.07 Hz

    but i am not sure if this is the right answer.

    The formula is correct for the reactance, but the value for frequency that you found doesn't look right. Check your math.
