Reactance increase means the value of the inductance is already increased because thease two factors are directly proportional to eachother. we can see from the formula ; inductive reactance xL =2(3.14)FL

What is the unit of measurement of inductive reactance?
Reactance is measured in ohms. By convention inductance produces a positive reactance while capacitance has a negative reatance. This is a convention that is consistent with a time-dependecy 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)
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
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.
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
What is the units of inductance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
Does frequency effect total inductance?
Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.
What is inductive reactance-?
There is no such term as 'inductance reactance'; the correct term is 'inductive reactance'. This is the opposition to the flow of a.c. current, due to the inductance of the load, and the frequency of the supply, and is measured in ohms.Inductive reactance is directly proportional to both the supply frequency and the load's inductance.
What will be the voltage in an inductance reactance circuit?
The voltage across the inductance alone will be(value of the inductance) times (the rate at which the current through it changes)
If a coil has 100 microhenries inductance at 400 hertz what is it's reactance?
0.2512 OHMS
What is the unit of measurement of inductive reactance?
Reactance is measured in ohms. By convention inductance produces a positive reactance while capacitance has a negative reatance. This is a convention that is consistent with a time-dependecy of exp(+jwt).
What is synchronous reactance?
Synchronous Reactance (in a generator analysis domain) is and equivalent series per-phase inductance term (think per-phase winding resistance) and is mainly composed of the machine's per-phase leakage inductance (equivalent series inductance of primary and secondary flux leakage) and armature reaction (distortion in flux introduced by an armature current in a machine, once again on a per-phase basis; described as a series inductance). L_SyncReac=L_leakage+L_ArmatureReaction. That sort of touches the surface of synchronous reactance.
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)
How reactance of inductors depends on frequency?
actually, inductance is directly proptional to the frequency according to the formula , so if frequency is more, then inductance is also more and vice versa
Can you apply law of ohm in alternating current and voltage?
Yes, but you need to convert inductance and capacitance to reactance.
Why DC motor does not have reactance?
Reactance is a result of inductance. Inductance is a result of a changing magnetic flux cutting a wire or let say, a coil, or, a result of a moving conductor cutting a magnetic field. DC motors are inductors i.e they have reactance. This happen as soon as the armature starts rotating. The armature is moving in the magnetic field of the field windings thus an emf is induced in them as the armature conductors start cutting the field. It's this emf that limits the armature current once the motor is in motion.
