Inductors, also known as coils or chokes, are essential components in electrical circuits. Their primary function is to store and release energy in the form of magnetic fields. In this comprehensive guide, we explore the fundamentals of inductance and impedance, helping readers develop a solid understanding of these vital components in electronic devices.
The key performance specifications of inductors include their inductance value, power capacity, and impedance. Inductance is achieved through electromagnetic induction, where an electric current generates a magnetic field that induces a current in nearby conductors. Inductors demonstrate self-inductance, where the magnetic field produced by an electric current interferes with the current itself. They also exhibit mutual inductance, where the magnetic field produced by one inductor induces a current in another nearby conductor.
The electrical characteristics of inductors impact their impedance, which varies with frequency. Inductors exhibit low impedance at low frequencies, allowing low-frequency signals to pass through them easily while impeding high-frequency signals.
Transformers are an essential application of inductors. They use mutual inductance to transfer electrical energy from one circuit to another. By changing the voltage and current levels, transformers can convert AC power to DC voltage or vice versa.
