Inductors
Inductors are passive electronic components that store energy in a magnetic field when electric current flows through them. They play an essential role in power supplies, filters, radio-frequency circuits, motor controllers, audio equipment and many other electronic systems. This comprehensive guide explains how inductors work, the different types available, their characteristics, practical applications, testing methods and repair techniques.
