What is the value of inductance L for which the current is maximum in a series LCR circuit with C=10 F and =1000 s ⁻¹ ?

Options

  1. A1 mH
  2. Bcannot be calculated unless R is known
  3. C10 mH
  4. D100 mH .

Correct answer

D. 100 mH .

Step-by-step solution

According to question current is maximum at resonance aligned ^2 & = 1 L C L & = 1 ^2 C & = 1 (1000)^2 (10 10⁻⁶ ) & =0.1 H =100 mH aligned
