3. It is impossible to change the current through an inductor by a finite amount in zero time for this requires an infinite voltage across the inductor. It will be advantageous later to hypothesize that such a voltage may be generated or applied to an inductor, but for the present we shall avoid such a forcing (Fh) function or response (HaM) An inductor resists an abrupt change in the current through it in a manner analogous to the way a mass resists an abrupt change in its velocity 4. The inductor never dissipated energy, but only stores it. Although this is true for the mathematical model, it is not true for a physical inductor.An inductor resists an abrupt change in the current through it in a manner analogous to the way a mass resists an abrupt change in its velocity. 3.
