In AC circuits, inductors continuously oppose changes in current, leading to a phase shift between voltage and current. The current lags behind the voltage, which can be represented using the formula:
- V = L (di/dt)
Applications of Inductors
Inductors are used in various applications across different fields. Here are some common uses:
- Filters in radio frequency circuits

Inductors are crucial components in electrical circuits, yet they often remain a mystery to many students and educators. In this article, we will explore the fundamental aspects of inductors, their behavior in circuits, and their practical applications.
What is an Inductor?
An inductor is a passive electrical component that stores energy in a magnetic field when electric current flows through it. The basic structure of an inductor typically consists of a coil of wire, often wrapped around a core material, which can be air, iron, or ferrite.
How Inductors Work
The operation of inductors is based on the principle of electromagnetic induction. When the current through an inductor changes, it creates a changing magnetic field. This changing magnetic field induces a voltage in the opposite direction, which is known as back EMF (electromotive force).
