An inductor is ingeniously crafted to accumulate energy within its magnetic field. This field is a direct result of the current that meanders through its coiled structure. When this current maintains a steady state, there is no detectable voltage across the inductor, prompting it to mimic the behavior of a short circuit when faced with direct current terms of gauging …
Energy Storage. The energy of running current through an inductor is stored as a magnetic field. In other words, if we turn on a voltage and current flows through an inductor, then a magnetic field will form. That magnetic field represents the energy in an inductor that we spent in creating it with voltage and current.
