Homework Help: Frequency of oscillation

  1. Jul 17, 2010 #1
    1. The problem statement, all variables and given/known data
    A resistance of 100 ohm is connected in series with capacitor 0.1 microF and an inductance 10 mH. find the frequency of oscillation and value of current at resonance?

    2. Relevant equations

    f= 1 / 2*pi*sqrt(LC)

    3. The attempt at a solution
    i think the formula i use for frequency of oscillation is correct. but how do i find the value of current at resonance. will it be I= V/R. because it resonance Xl=Xc so they cancel each other so the circuit will be purely resistance. kindly suggest.

    You are correct in your thinking, however the problem as you stated it doesn't say what V is, so you cannot find the current.
