When an inductor is exposed to a current with a specific polarity, it attempts to oppose the current while the current is stored inside the inductor as magnetic energy.
The resistance of the inductor is at its maximum at the beginning of the DC application and gradually decreases and moves towards zero resistance with time, eventually reaching zero-ohm after some specified time depending on the magnitude of the inductance.
This response is exponential, meaning gradually varying with time (directly proportional).
As soon as the storage phase is over, the current, , that flows through is stable, , no self-induced is generated, and is zero, an inductor is comparable to a short circuit to direct current. The inductor behaves like a regular connecting wire since it has no resistance.
Hence, when connected to a DC circuit, the inductor is equivalent to a short circuit. In a DC circuit, the inductor behaves just like a regular connecting wire with no resistance.
