Homework Statement


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?


Homework Equations



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

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.
