AC Inductor Circuits | Reactance and Impedance—Inductive
Mathematically, we say that the phase angle of an inductor''s opposition to current is 90°, meaning that an inductor''s opposition to current is a positive imaginary quantity. This phase angle of reactive opposition to current becomes critically important in circuit analysis, especially for complex AC circuits where reactance and resistance interact.
Inductor and Capacitor Basics | Energy Storage Devices
These two distinct energy storage mechanisms are represented in electric circuits by two ideal circuit elements: the ideal capacitor and the ideal inductor, which approximate the behavior of actual discrete capacitors and inductors. They also approximate the bulk properties of capacitance and inductance that are present in any physical system.

23.2: Reactance, Inductive and Capacitive
For inductors in AC circuits, we find that when a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle, or by a (90^o) phase angle. The opposition of an inductor to a change in current is expressed as a type of AC resistance.

An inductor can also be known as a coil, reactor, or choke. It is a two-terminal component that stores energy in a magnetic field when current is flowing through it. A standard inductor normally consists of an insulated wire …
Inductors: What Are They? (Worked Examples Included)
Inductors are typically available in the range from 1 µH (10-6 H) to 20 H. Many inductors have a magnetic core made of ferrite or iron inside the coil, which is used to increase the magnetic field and thus the inductor''s inductance.. According to Faraday''s law of electromagnetic induction, when the current through an inductor changes, the varying …
Inductance of a Coil
Where: L is the inductance in Henries, V L is the voltage across the coil and di/dt is the rate of change of current in Amperes per second, A/s. Inductance, L is actually a measure of an inductors "resistance" to the change of the current flowing through the circuit and the larger is its value in Henries, the lower will be the rate of current change.
