Inductive reactance, XL, in ohms, is given by:
XL = 2 pi f L
where:
f = frequency (Hz)
L = inductance (H)
VAr is reactive power, caused by either inductive or capacitive loads. The ideal power factor to have is 1, anything less than that is a loss on the network. The effect of VArs on the circuit though depends. If you have a load that is mainly inductive, then adding more inductive reactance will lower the power factor. However, if you introduce capacitive reactance this will increase the power factor, and the opposite is true if its a mainly capacitive circuit. So VArs will either increase or decrease the power factor depending on the load of the circuit. The ideal situation is to balance inductive reactance with capacitive reactance so they in effect cancel each other out and power factor is 1.
The unit of measurement for inductive reactance (XL) is the ohm.
The inductive reactance of a 15 Henry inductor at 60 Hz is about 5.7 KOhms. (2 pi f l)
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
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.
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!
The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.
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
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The symbol for inductive reactance is XL.
Current Flow I believe.
Series resonance occurs when a circuit's inductive reactance is equal to its capacitive reactance. The resistance of the circuit is irrelevant.WebRep currentVote noRating noWeight
yesAnswerNo, but you can counter its effects. For example, if your load is inductive, then you can counter the effects of its inductive reactance by introducing capacitors with equal capacitive reactance.
Inductive reactance.
Resistance, capacitive reactance, inductive reactance. Note: None of this is really a "force" - not in the meaning of "force" as used in physics.
