Inductance of a Coil

Defining the equation for an inductor as being V L = L(di/dt). You state that a "DC current can be controlled an active inductor", and as previously described that an inductive coil opposes a change in current through it. DC current will build-up slowly to its maximum at a rate determined by the time constant of the RL circuit.

Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) in the conductor
