22.2: AC Circuits
X L is called the inductive reactance. Because the inductor reacts to impede the current, X L has units of ohms (1 H=1 Ωs, so that frequency times inductance has units of (cycles/s)(Ωs)=Ω), consistent with its role as an effective resistance.
AC Inductor Circuits | Reactance and Impedance—Inductive
Inductive reactance is the opposition that an inductor offers to alternating current due to its phase-shifted storage and release of energy in its magnetic field. Reactance is symbolized by the

Inductive & Non-Inductive Circuits Questions and Answers
This set of Basic Electrical Engineering Multiple Choice Questions & Answers (MCQs) focuses on "Inductive and Non-Inductive Circuits". 1. In case of Inductive circuit, Frequency is _____ to
23.2: Reactance, Inductive and Capacitive
Inductive reactance (X_L) has units of ohms and is greatest at high frequencies. For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase

A circuit with resistance and self-inductance is known as an RL circuit gure (PageIndex{1a}) shows an RL circuit consisting of a resistor, an inductor, a constant source of emf, and switches (S_1) and (S_2). When (S_1) is
Inductive Reactance
Therefore Inductive reactance is equal to 2?fL where, reactance is directly proportional to frequency of signal. This is the reason why inductor acts as closed switch in DC circuit since frequency of DC is 0 and hence reactance

with the frequency of the AC voltage source in hertz (An analysis of the circuit using Kirchhoff''s loop rule and calculus actually produces this expression). is called the inductive reactance,
Reactance, resistance, & impedance (what''s the difference?)
The opposition offered by capacitors and inductors to alternating currents is called reactance. Reactance values depend on frequency while resistances don''t. Reactances resist currents
6 FAQs about [Maximum energy storage of inductive reactance]
What is inductive reactance?
Just like resistance, the value of reactance is also measured in Ohm’s but is given the symbol X, (uppercase letter “X”), to distinguish it from a purely resistive value. As the component we are interested in is an inductor, the reactance of an inductor is therefore called “Inductive Reactance”.
How do you calculate the energy stored in an inductor?
The energy ($U$) stored in an inductor can be calculated using the formula: $$U = \frac {1} {2} L I^2$$, where $L$ is the inductance and $I$ is the current. Inductors resist changes in current due to their stored energy, which can lead to time delays in circuits when switching occurs.
What is inductive resistance in AC circuit?
In other words, an inductors electrical resistance when used in an AC circuit is called Inductive Reactance. Inductive Reactance which is given the symbol XL, is the property in an AC circuit which opposes the change in the current.
What is inductive reactance of a coil?
Inductive Reactance of a coil depends on the frequency of the applied voltage as reactance is directly proportional to frequency Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance.
What is energy storage in inductors?
Energy storage in inductors is vital for various applications in electrical engineering, such as power supplies, filtering, and signal processing. Inductors help smooth out fluctuations in power supply by storing excess energy during high demand and releasing it during low demand.
What are stray resistive properties of a real inductor?
Altogether, the stray resistive properties of a real inductor (wire resistance, radiation losses, eddy currents, and hysteresis losses) are expressed under the single term of “effective resistance:” Equivalent circuit of a real inductor with skin-effect, radiation, eddy current, and hysteresis losses.
