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).'
Inductive reactance, as well as capacitive reactance, is measured in ohms.
Inductive reactance.
The quantity symbol for reactance is X.
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.
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The unit of measurement for inductive reactance (XL) is the ohm.
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
