Energy stored inside the inductor is given by _.

Correct answer: A. (1/2)LI^2

  • A. (1/2)LI^2
  • B. LI^2
  • C. (3/2)Ll^2
  • D. LI

Explanation

An inductor carrying current is analogous to a mass having velocity. So, just like a moving mass has kinetic energy = 1/2 mv2, a coil carrying current stores energy in its magnetic field giving by 1/2 LI2.

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
