Inductive Reactance Wikipedia

Reactance psychology an emotional reaction to pressure or persuasion that results in the strengthening or adoption of. For an ideal inductor in an ac circuit the inhibitive effect on change in current flow results in a delay or a phase shift of the alternating current with respect to alternating voltage.

Reactance may refer to.

Inductive reactance wikipedia. The term complex impedance may be used interchangeably. In the context of an ac circuit although this concept applies any time current is changing this magnetic field is constantly changing as a result of current that oscillates. In this case actually working useful parameter is not the leakage inductance value but the short circuit inductance value.

The imaginary component of ac impedance. Electrical reactance the opposition to a change in voltage due to capacitance capacitive reactance or in current due to inductance inductive reactance. The voltage of the capacitor or inductor can be expressed in.

In the si system it is measured in units of w 1. Quantitatively the impedance of a two terminal circuit element is the ratio of the complex representation of a sinusoidal voltage between its terminals to the complex representation of the current flowing through it. Specifically an ideal inductor with no resistance will cause the.

Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. The q factor of an inductor is defined as where l is the inductance r is the dcr and the product wl is the inductive reactance. It is defined analogously to electrical resistance in a resistor as the ratio of the amplitude peak value of the alternating voltage to current in the component reactance has units of ohms.

In electric power systems inductive reactance and capacitive reactance however inductive reactance is more common can limit the power capacity of an ac transmission line because power is not completely transferred when voltage and current are out of phase detailed above. Magnetic reactance a similar effect in magnetism. Inductive reactance is the opposition of an inductor to an alternating current.

Inductive reactance is a property exhibited by an inductor and inductive reactance exists based on the fact that an electric current produces a magnetic field around it. Although they are constant at low frequencies the parameters vary with frequency. In the context of the gyrator capacitor model of a magnetic circuit magnetic inductance inductive magnetic reactance is the analogy to inductance in an electrical circuit.

Q increases linearly with frequency if l and r are constant. Transformers are generally designed to have a specific value of leakage inductance such that the leakage reactance created by this inductance is a specific value at the desired frequency of operation. Hence inductive reactance is an opposition to the change of current through an element.

The reactance x x x of a circuit is the apparent resistance contributed to a circuit by the capacitor and inductorboth capacitors and inductors are in truth resistance less so they do not directly resist the current but their interactions with the resistor and voltage source can be modeled in dimensionally equivalent terms.
