The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.
The electrical term reactance speaks to the "resistance" to AC in a circuit (though it isn't resistance) because of the presence of inductive and capacitive components in that circuit. Reactance can be either inductive or capacitive, and in each case we investigate, energy is taken from the circuit and then returned to the circuit, but at different times. Additionally, in the case of inductive reactance, the energy is stored in the form of a magnetic field. In capacitance reactance, the energy is stored in the form of electric charge.
When we consider the manner in which these two types of reactance operate, we might consider that they are actually complimentary. To cite a single example, when an inductor and a capacitor are in parallel in a circuit, they form a parallel tank circuit. In this circuit, the inductor and capacitor are taking energy and storing it, and then returning that energy back into the circuit at "opposite" times relative to each other. This allows the tank to "ring" or "oscillate" with a current circulating within the tank when it is at resonance. Links can be found below to begin investigating these phenomenon.
CommentIt might be better is reactance is equated to 'opposition' of a circuit, rather to its 'resistance'. The problem with the term 'resistance' is, that while (as in the above answer) it can be used in the sense of 'opposition', it has a very specific meaning in electrical engineering and, therefore, its use can be misinterpreted.
The reciprocal of reactance is susceptance, expressed in siemens.
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
The unit of measurement for inductive reactance (XL) is the ohm.
Since capacitive reactance is inversely-proportional to the supply frequency, as the frequency is increased, the reactance will decrease.
The capacitive reactance of a capacitor increases as the frequency decreases.
Inductive reactance, as well as capacitive reactance, is measured in ohms.
Inductive reactance.
The reciprocal of reactance is susceptance, expressed in siemens.
The symbol for inductive reactance is XL.
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
The overall reactance of the armature winding is the sum of its leakage reactance plus fictitious reactance, which is known as synchronous reactance (Xs).Xs=XL+Xarwhere XL and Xar are in Ω/phase. Therefore, Xs is in Ω/phase.The impedance of armature winding is obtained by combining its resistance and its synchronous reactance.
Inductive reactance does NOT have it own sign or symbol. Rather, it uses Ohms as a quantifier. But Capacitive reactance ALSO uses Ohms as a quantifier. Fortunately, 1 Ohm of Inductive reactance is cancelled by 1 Ohm of Capacitive reactance at the same frequency of measurement.
Because it is. Capacitive reactance is a form of resistance, along with inductive reactance. All are measured in ohms.
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The unit of measurement for inductive reactance (XL) is the ohm.
by adding the opposite type of reactance. as motors are a common industrial load and their reactance is inductive, add capacitive reactance.
