Question

The resonant frequency of a circuit is f. If the capacitance is made 4 times the initial values, then the resonant frequency will become

  1. f / 2    
  2. 2f    
  3. f    
  4. f / 4    

The correct answer is: f / 2


    f equals fraction numerator 1 over denominator 2 pi square root of L C end root end fraction Þ f proportional to fraction numerator 1 over denominator square root of C end fraction
