Two inductors of 60 mH each are joined in parallel. The current passing through this combination is 2.2 A. The energy stored in this combination of inductors in joule is (a) 0.0333 (b) 0.0667 (c) 0.0726 (d) 0.0984

Answer: (c). Parallel: Lp = 60/2 = 30 mH. U = 1/2× 0.03 × (2.2)² = 0.015 × 4.84 = 0.0726 J So the answer is (c) 0.0726.

Self-Inductance & Energy

Two inductors of $60\text{ mH}$ each are joined in parallel. The current passing through this combination is $2.2\text{ A}$ . The energy stored in this combination of inductors in joule is

Show answer and solution

Answer: (c)

Parallel: $L_p = \dfrac{60}{2} = 30$ mH.
$U = \dfrac{1}{2}\times 0.03 \times (2.2)^2 = 0.015 \times 4.84 = 0.0726$ J
So the answer is (c) 0.0726.
