It's called the reactance theory.
Reactance reaction reactionaries reactionary reactionist.
Impedance is the sum of the resistance and reactance of an electrical circuit.
R55 and reactance component X55.
In a simple capacitive/resistive low-pass filter, it is the frequency at which capacitive reactance in ohms equals resistance in ohms.
Thus, the reactance formula XL= 2πfL could also be written as XL= ωL.
Input impedance has resistor heft Rin and reactance heft Xin, namely Zin= Rin+ J Xin.
The reactance is divided into inductive reactance and capacitive reactance.
Please note that the relationship of capacitive reactance to frequency is exactly opposite from that of inductive reactance.
Impedance is a comprehensive expression of any andall forms of opposition to electron flow, including both resistance and reactance.
We must control the resistance and reactance of an electrical circuit to ensure the quality of signal in the complex design.
However in high speed AC circuits(those with sharp changes in voltage and/or current) the reactance and thus the impedance can become very significant.
As with inductors, the reactance of a capacitor is expressed in ohms and symbolized by the letter X(or XC to be more specific).
The capacitor is sized to have approximately the same amount of reactance at system frequency as each lamp's resistance.
Any resistance or reactance is captured by explicitly adding a parasitic element, such as a discrete resistor or inductor.
They are also often used forpower supply rail decoupling in parallel with film or ceramic capacitors which provide low ESR and low reactance at high frequency.
What this means is that reactance in ohms for any inductor is directly proportional to the frequency of the alternating current.
Or the resistance of electromagnetic waves during propagation is called characteristic impedance, which is actually a vector sum of electrical impedance, inductance,and capacitive reactance.
This opposition to voltage change is another form of reactance, but one that is precisely opposite to the kind exhibited by inductors.
Because inductive reactance increases with increasing frequency and capacitive reactance decreases with increasing frequency, there will only be one frequency where these two reactances will be equal.
The main reason for not finding the resonance point is that the capacitance of the test object does not match the amount of reactance, and the resonance point caused by the resonance condition exceeding the resonance frequency cannot be found.
Any resistance and any reactance, separately or in combination(series/parallel), can be and should be represented as a single impedance in an AC circuit.
Power capacitors that are sensitive to harmonic frequencies, due to their own capacitive impedance characteristics, andinversely proportional to frequency and capacitive reactance, make harmonic currents easily absorbed by power capacitors and cause capacitor thermal overload.
This technique relies on the psychological phenomenon of reactance, in which a person has a negative emotional reaction to being persuaded, and thus chooses the option which is being advocated against.
After the current is stabilized, the microcomputer system obtains the voltage and current waveform data through the A/D converter, and performs digital filtering to calculate Voltage V45 and current I45 and their phase difference, further calculate impedance Z45,resistance component R45 and reactance component X45.
The impedance Z is the vector sum of reactance and resistance; it describes the phase difference and the ratio of amplitudes between sinusoidally varying voltage and sinusoidally varying current at a given frequency.
