Homework Help: Series rlc circuit question

  1. May 3, 2005 #1

    im in first year electronics and have a problem with a parallel rlc circuit

    im trying to find the reactance (Xc and Xl) for a circuit that has a 500 ohm resister and a .01 microfarad capacitor in parallel with a 500 ohm resistor and a .5 mH inductor. The frequency of the circuit is 50 KhZ

    here are my calculations

    xc= 1/(2)(pie)(50khz)(.01microfarads)
    = 0.32

    xl= (2)(pie)(50khz)(.0005H)

    but i had them both marked wrong...help with this would be very much appreciated

    You have used the right approach to work out the capacitive reactance and inductive reactance but you have to check your math. You are out by a factor of 1000 in each case.

    To find the total reactance you have to subtract the capacitive from the inductive reactance.
