it is a internal resistance of the devices like as capacitor and inductor
CommentAs 'resistance' has a very specific meaning, I suggest that the above answer should read: 'It is the opposition of devices like capacitors and inductors (to the flow of current).'

What is the unit of inductive reactance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
What does capacitive reactance oppose?
Inductive reactance.
What is the inverse of reactance?
The reciprocal of reactance is susceptance, expressed in siemens.
What are the letters for Inductive Reactance?
The symbol for inductive reactance is XL.
How does doubling the frequency effect the reactance of an inducter and capacitor?
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.
What is synchronous reactance in alternator?
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.
What is the symbol for inductive 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.
What is the reason that capacitive reactance measured in ohms?
Because it is. Capacitive reactance is a form of resistance, along with inductive reactance. All are measured in ohms.
What is difference in resistance and reactance?
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
What is the units of inductance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The unit of measure of inductive reactance?
The unit of measurement for inductive reactance (XL) is the ohm.
How is the power factor improved in an AC system?
by adding the opposite type of reactance. as motors are a common industrial load and their reactance is inductive, add capacitive reactance.
