Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.

The unit of measure of inductive reactance?
The unit of measurement for inductive reactance (XL) is the ohm.
What is the phase relationship of capacitive and inductive reactance?
Inductive reactance is traditionally positive while capacitive reactance is traditionally negative. Those are the conventions used by electrical engineers and they are consistent with a time-dependency of exp(+jwt).
How do compute the reactance in an inductive circuit?
Inductive reactance, XL, in ohms, is given by:XL = 2 pi f Lwhere:f = frequency (Hz)L = inductance (H)
What is the symbol for induction?
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.
Why does an inductor block AC but allow DC?
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
What is the unit of inductive reactance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
What are the letters for Inductive Reactance?
The symbol for inductive reactance is XL.
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 does capacitive reactance oppose?
Inductive reactance.
Does reactance increase with an increase in inductance?
Inductive reactance case of ac) is equivalent to resistance (in case of dc) for inductors.So if resistance increases current decreasesas well as if inductive reactance increases current decreases
Why inductor and capacitor works only for alternating currents?
Actually they work fine for both AC and DC, its just that DC is the limiting case where the inductive reactance falls to zero and the capacitive reactance rises to infinity.The other limiting case is infinite frequency (but of course this is not reached in practice, but if it could they work fine too) where the inductive reactance rises to infinity and the capacitive reactance falls to zero.
The unit of measure of inductive reactance?
The unit of measurement for inductive reactance (XL) is the ohm.
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.
Why is capacitive voltage higher than inductive voltage in an R-L-C circuit?
It isn't necessarily so. The capacitive voltage is the product of the current and capacitive reactance, while the inductive voltage is the product of the current and the inductive reactance. So it depends whether the capacitive reactance is greater or smaller than the inductive reactance!
What are capacitive and inductive reactance?
yyiiiiii
What is the unit inductive reactance?
ohms
Will an inductor work on DC?
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
