Inductors & DC Transients (Mixed)

The magnetic energy stored in an inductor of inductance 4 μH4\,\mu\text{H} carrying a current of 2 A2\text{ A} is:

Show answer and solution

Answer: (c)

  1. U=12LI2U = \frac{1}{2}LI^2
  2. U=12(4×10−6)(2)2=8×10−6 JU = \frac{1}{2}(4\times10^{-6})(2)^2 = 8\times10^{-6}\text{ J}
  3. So the answer is (c) 8 μJ8\,\mu\text{J}.
