Description

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

$\displaystyle v = L \frac{dI}{dt}$

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.
