Introduction to Inductors
Inductors are passive electronic components that store energy in a magnetic field when an electric current flows through them. They are fundamental building blocks in electronic circuits, playing crucial roles in various applications such as power supplies, filters, oscillators, and signal processing. The basic principle of an inductor is based on Faraday's law of electromagnetic induction. When the current through an inductor changes, it induces an electromotive force (EMF) that opposes the change in current. This property makes inductors useful for smoothing out current fluctuations, filtering out unwanted frequencies, and storing energy temporarily.
The performance of an inductor is characterized by several parameters, including inductance (measured in henries, H), resistance, quality factor (Q), and self - resonant frequency. Different types of inductors are available, such as air - core inductors, iron - core inductors, and ferrite - core inductors, each with its own advantages and applications.
