Formule

## Energy in an Inductor An inductor stores energy in its magnetic field when current flows through it. ### Formula **E = (1/2) * L * I²** This energy is released when the current decreases. The magnetic field collapses, driving current through the circuit.

Exemple Résolu

A 100 mH inductor carrying 2 A.

  1. 01E = 0.5 * L * I²
  2. 02E = 0.5 * 100e-3 * 4
  3. 03E = 0.5 * 0.4
  4. 04E = 0.2 J = 200 mJ
