### Description

Inductor is an electrical component that can store energy in electrical circuits. The relationship between the voltage across the ports of an inductor of inductance and the current passing through it is given by:

Inductors can also be used to differentiate between high-frequency and low-frequency signals and this makes them useful in electronic filters. An inductor shows a hight impedence for hight frequency signals.
