Want this question answered?
capacitive reactance is inversely proportional to the capacitance of the capacitor and frequency of the AC line reactance (in ohms) = 1/(capacitance * frequency)
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
There is pure resistance, inductive reactance, and capacitive reactance.
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.
Resistance, capacitive reactance, inductive reactance. Note: None of this is really a "force" - not in the meaning of "force" as used in physics.
yes, capacitive reactance is inversely proportional to frequency.
The simple answer is no. The impedance of an R-Lcircuit is the vector sum of the circuit's resistance and its inductive reactance. Resistance is determined by the length, cross-sectional area, and resistivity of the conductor (although its 'a.c. resistance' is proportional to the frequency squared), whereas the inductive reactance is directly proportional to the frequency of the supply.
Since capacitive reactance is inversely-proportional to the supply frequency, as the frequency is increased, the reactance will decrease.
inverse of frequencyAnswerReactance is inversely-proportional to frequency of the supply, and the capacitance of the capacitor.
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.

It depends on the nature of the load.For inductive loads, the current will fall, because inductive reactance is directly-proportional to frequency.For capacitive loads, the current will increase, because capacitive reactance is inversely-proportional to current.For resistive loads, there will be very little change in current unless the frequency is changed substantially. This is because, at higher frequencies, the 'a.c. resistance', due to the 'skin effect', will increase.
It is the capacitive reactance of a capacitor that causes it to oppose the passage of a.c. current. Since capacitive reactance is inversely-proportional to frequency, the lower the frequency, the greater its reactance, and the more it will oppose the flow of a.c.
A capacitor will oppose the flow of a.c. due to its capacitive reactance (Xc), expressed in ohms.The capacitive reactance for a given capacitor is inversely-proportional to the frequency of the supply; in other words, the higher the frequency, to lower the capacitive reactance.
Impedance (Z) is the vector sum of a circuit's resistance (R) and reactance(X), is expressed in ohms, and is the total opposition to current in an a.c. circuit.Resistance, expressed in ohms, depends upon the length, cross-sectional area, and resistivity of the conductor.Reactance, expressed in ohms, can be inductive reactance (XL), capacitive reactance(XC), or a combination (vector sum) of the two.Inductive reactance is directly proportional to the circuit's inductance and the supply frequency.Capacitive reactance is inversely proportional to the circuit's capacitance and the supply frequency.
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
Xc(capacitive reactance) = 1/(2piFC)XL(inductive reactance) = 2piFLWhere pi=3.14etc.,F=frequency and C and L are capacitance and inductance.Please pardon lack of proper symbology.
