The dynamic resistance of an AC circuit is described by the term impedance, for which ohms is also the unit of measure. This impedance in AC circuits is caused by the reluctance of the inductor, which is the wound magnetic coil within the circuit, to pass current above a certain predefined frequency, as the magnetic field generated by the inductor acts as canceling momentum upon itself. As a result, this dynamic resistance increases to a point where current can no longer flow through the inductor, despite the voltage being applied to it.
