A series resonant circuit consists of inductor ' L ' of negligible resistance and a capacitor ' C ' which produces resonant frequency ' f '. If L is changed to 3 L and ' C ' is changed to 6 C , the resonant frequency will become.

Options

  1. Af 6
  2. Bf 3
  3. Cf 2 2
  4. Df 3 2

Correct answer

D. f 3 2

Step-by-step solution

Resonant frequency, f= 1 2 L C If L becomes 3 L and C becomes 6 C , then the frequency will become f^ = 1 2 3 L 6 C = 1 2 3 2 LC = f 3 2
