• Resumen

  • As an inductor demagnetizes through a resistor, the area under the curve in the current squared vs. time graph allows for the calculation of the magnetic energy that was stored in the inductor. Its dependence on the initial electric current yields the self-inductance with good accuracy and small uncertainty.
