What is the Quantity Symbol for Reactance?
The quantity symbol for reactance is X.
Is inductive reactance directly or inversely proportional to frequency?
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
What factors affect the reactance of a capacitor?
Reactance (in ohms) = 1/(2 pi * capacitance * frequency). Capacitance is in farads. Frequency is in Hertz (cycles/second). So increasing capacitance or increasing frequency will decrease reactance.
Is the Reactance of aluminum conductors the same of copper conductors?
No, the reactance of aluminum conductors is not the same as copper conductors. Aluminum has a higher resistivity than copper, which results in different reactance values for the two materials. The reactance of a conductor depends on its material properties and dimensions.
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
Foster's Reactance theorem in network theory?
Foster's reactance theorem is a significant hypothesis in the fields of electrical system investigation and combination. The hypothesis expresses that the reactance of a detached, lossless two-terminal (one-port) arrange in every case carefully monotonically increments with recurrence.

What is the unit of inductive reactance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
What does capacitive reactance oppose?
Inductive reactance.
What is total impedance of a circuit when the resistance is 15k ohms and the capacitive reactance is 10k ohms?
You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms. ("j" is used instead of "i", to avoid confusion with current, which is symbolized by "i".) This is in rectangular coordinates; with a scientific calculator you can use rectangular --> polar conversion, to get the absolute value and the angle. To get just the absolute value, use Pythagoras' Theorem, which in this case gives about 18 kilohms.You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms.

Can a capacitor be used in the Thevenin Theorem?
Sure, but it won't mean anything unless the Thevenin source is an AC source. In that case, simply determine the frequency of the source, and draw the appropriate reactance in the circuit where the capacitor belongs. If the Thevenin source is DC, then the frequency is zero, the reactance of the capacitor is infinite, and you can show it as an open circuit, i.e. not there.
What is the Quantity Symbol for Reactance?
The quantity symbol for reactance is X.
What are the letters for Inductive Reactance?
The symbol for inductive reactance is XL.
What is the inverse of reactance?
The reciprocal of reactance is susceptance, expressed in siemens.
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.
What is synchronous reactance in alternator?
The overall reactance of the armature winding is the sum of its leakage reactance plus fictitious reactance, which is known as synchronous reactance (Xs).Xs=XL+Xarwhere XL and Xar are in Ω/phase. Therefore, Xs is in Ω/phase.The impedance of armature winding is obtained by combining its resistance and its synchronous reactance.
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.
What is the reason that capacitive reactance measured in ohms?
Because it is. Capacitive reactance is a form of resistance, along with inductive reactance. All are measured in ohms.
