A constant direct current has a zero rate-of-change, and sees an inductor as a short-circuit (it is typically made from a material with a low resistivity ).
A few types: :*Tank coil - an inductor used in a tuned circuit :* Choke - an inductor used to block high frequency AC while allowing through low frequency AC.
Also, phasor analysis of circuits can include Euler's formula to represent the impedance of a capacitor or an inductor.
A double-conversion UPS with an insulated-gate bipolar transistor rectifier and inductor can have a THD I as small as 2%.
At increasing frequency, on the other hand, the reactance increases and at a sufficiently high frequency the inductor approaches an open circuit.
At low frequency the reactance falls, and for a steady current (zero frequency) the inductor behaves as a short-circuit.
