Inductors are essential components widely used in electronic systems.
Firstly, they resist sudden changes in current due to self-induced voltage, making them suitable for both high- and low-frequency choke applications.
Secondly, they are widely used in LC resonant circuits for tuning and frequency selection, where resonance allows specific signals to be isolated and amplified.
Thirdly, inductors act as chokes, blocking unwanted AC components in low-frequency circuits and suppressing high-frequency noise in RF systems.
In addition, they are critical in power filtering circuits, working with capacitors to smooth rectified DC outputs and reduce ripple.
Finally, inductors are used in oscillators, which convert DC into AC waveforms, supporting a wide range of signal generation from low Hz to GHz levels.
