	What is reactance? - a definition from Whatis.com
		Resistance and reactance combine to form impedance, which is defined in terms of two-dimensional quantities known as complex number.
		As the inductance of a component increases, its inductive reactance becomes larger in imaginary terms, assuming the frequency is held constant.
		As the capacitance of a component increases, its capacitive reactance becomes smaller negatively (closer to zero) in imaginary terms, assuming the frequency is held constant.

	Reactance
		In the analysis of an alternating-current electrical circuit (for example a RLC series circuit), reactance is the imaginary part of impedance, and is caused by the presence of inductors or capacitors in the circuit.
		Reactance produces a phase shift between the electric current and voltage in the circuit.
		Reactance is denoted by the symbol X and is measured in ohms.

	reactance - a definition from Whatis.com
		Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance.
		As the inductance of a component increases, its inductive reactance becomes larger in imaginary terms, assuming the frequency is held constant.
		As the capacitance of a component increases, its capacitive reactance becomes smaller negatively (closer to zero) in imaginary terms, assuming the frequency is held constant.

	Reactance - Wikipedia, the free encyclopedia
		In the analysis of an alternating-current electrical circuit (for example a RLC series circuit), reactance is the imaginary part of impedance, and is caused by the presence of inductors or capacitors in the circuit.
		Reactance is the component of complex electric impedance of the alternating current circuit, which produces a phase shift between an electric current and voltage in the circuit.

	Capacitive Reactance
		The reactance is inversely proportional to both the frequency and the capacitance.
		Reactance is different from resistance because reactance is an opposition that is manifested only be alternating current.
		Inductive reactance is measured in ohms and its symbol is XL.

	Resistance, Reactance, and Impedance (Site not responding. Last check: )
		Like resistance, reactance is expressed in ohms, and it behaves in much the same way as resistance, in the sense that it tends to restrict the flow of current through a circuit.
		X is the general electrical symbol for "reactance", and L is the symbol for "inductance" or "inductor", so put them together and you get the reactance of an inductor.
		XC is, as you might have guessed, the capacitive reactance, and C is the capacitance of the capacitor (in farads).

	Reactance
		Reactance is important to understand because it has strong motivational properties and leads to the final stage.
		It does no good to ignore the reactance, nor is it a good idea to fight the reactance.
		Fighting the reactance throws more fuel on the fire, giving the person an even stronger motivation to rebell, to resist, to deny.

	AC Capacitor Circuits - Reactance And Impedance - Capacitance
		Please note that the relationship of capacitive reactance to frequency is exactly opposite from that of inductive reactance.
		As with inductors, the reactance equation's 2πf term may be replaced by the lower-case Greek letter Omega (ω), which is referred to as the angular velocity of the AC circuit.
		Alternating current in a simple capacitive circuit is equal to the voltage (in volts) divided by the capacitive reactance (in ohms), just as either alternating or direct current in a simple resistive circuit is equal to the voltage (in volts) divided by the resistance (in ohms).

	Electrical theory, part 1
		Reactance is the part of total resistance that appears in AC circuits only.
		Reactance is represented by the letter “X.” The two types of reactance are inductive reactance and capacitive reactance.
		Inductive reactance is the resistance to current flow in an AC circuit, due to the effects of inductors in the circuit.

	Reactance Resolution
		When a reactance data point is found in a region of negative slope, the data is multiplied by -1 to flip the sign.
		From the previous section, the X Slope algorithm considers all positive slope reactance data to be positive, and all negative slope reactance data to be negative.
		Reactance resolution is a capture activity, not a graphing activity.

	AC Inductor Circuits - Reactance And Impedance - Inductors
		What this means in a practical sense is that the reactance of an inductor dissipates a net energy of zero, quite unlike the resistance of a resistor, which dissipates energy in the form of heat.
		Reactance to AC is expressed in ohms, just like resistance is, except that its mathematical symbol is X instead of R. To be specific, reactance associate with an inductor is usually symbolized by the capital letter X with a letter L as a subscript, like this: X
		Alternating current in a simple inductive circuit is equal to the voltage (in volts) divided by the inductive reactance (in ohms), just as either alternating or direct current in a simple resistive circuit is equal to the voltage (in volts) divided by the resistance (in ohms).

	BIODYNAMICS : Bioimpedance Measurements
		Impedance (Z) is the overall propensity of an object to conduct electrical current and is defined as the ratio of the voltage in an object to the current in an object.
		Reactance is the component of impedance related to the storage of energy in a conductive medium.
		The vector relationship between impedance, resistance, reactance, and phase angle, represented with polar coordinates is shown in the second figure.

	Harmonic compensator using low leakage reactance transformer - Patent 5341281
		Leakage reactance is a function of coil dimensions, winding-to-winding spacing, and the amount of primary to secondary coil area that is overlapped.
		Moreover, leakage reactance in conventional transformer structures is strongly coupled to the magnitude of the mutual or magnetizing inductance L.sub.m as seen in the transformer per phase equivalent circuit of FIG.
		Leakage reactance is reduced thereby because the constant internal flux linkage term of the governing L.sub.l equation is replaced by a term that is a function of inner and outer radii of the tube.

		The current passing through a reactance is not in phase with the applied voltage.
		For a capacitive reactance, the maximum charging current flows when the voltage across the capacitor is at its lowest value.
