Homework Help: Finding parallel resistance of an RLC circuit at resonance from V

  1. Apr 11, 2013 #1
    1. The problem statement, all variables and given/known data
    I need to be able to determine the equivalent parallel resistance of an RLC parallel circuit, from a measured voltage when the circuit is at resonance.

    2. Relevant equations

    3. The attempt at a solution
    I know the values of the circuit element, but I'm not sure how one is supposed to use V to determine the resistance here. This feels like an incredibly easy problem but I'm stuck. I know at resonance R_p = Z, (R_p as the equivalent parallel resistance). Any help would be great

    How is the circuit being driven (what's the source)?
