A magnetic field energy of \( 34 \times 10^{-6} \) J is stored in an inductor of inductance 1.7 mH in an LC circuit. The current flowing in the inductor is:

  1. A 0.141 A
  2. B 0.2 A
  3. C 1.41 A
  4. D 0.004 A
Verified Solution

Answer & Solution

Correct Answer

(B) 0.2 A

Step-by-step Solution

Detailed explanation

\( I = \sqrt{\frac{2E}{L}} \) \( I = \sqrt{\frac{2 \times 34 \times 10^{-6}}{1.7 \times 10^{-3}}} \text{ A} \) \( I = 0.2 \text{ A} \)
