Question

For the series LCR circuit shown in the figure, what is the resonance frequency and the amplitude of the current at the resonating frequency

  1. 2500 r a d minus s to the power of negative 1 end exponent and 5 square root of 2 A    
  2. 2500 r a d minus s to the power of negative 1 end exponent and 5 A    
  3. 2500 r a d minus s to the power of negative 1 end exponent and fraction numerator 5 over denominator square root of 2 end fraction A    
  4. 25 r a d minus s to the power of negative 1 end exponent and 5 square root of 2 A    

The correct answer is: 2500 r a d minus s to the power of negative 1 end exponent and 5 A


    Resonance frequency

    Resonance current = fraction numerator V over denominator R end fraction equals fraction numerator 220 over denominator 44 end fraction equals 5 A
