Capacitance is the capacity to store electric charges, usually a small amount of it, in a capacitor.Capacitive reactance is the reactance associated with a capacitor. Reactance is something that opposes the flow of current, in an AC circuit - but, unlike resistance, DOES NOT convert electrical energy into heat.

Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
When the frequency of an applied voltage is increased the capacitive reactance of a circuit will?
Since capacitive reactance is inversely-proportional to the supply frequency, as the frequency is increased, the reactance will decrease.
'when frequency is increased why capacitance increases in a capacitor'?
Answer: Capacitance is unaffected by frequency; it does not change. Details: Capacitance is unaffected by frequency. In a capacitor, what increases with Frequency is Admittance (analogus to Conductance) . The capacitive Reactance is inversely proportional to Frequency. Therefore, when Frequency is increased, current flow may increase.
What is the capacitive reactance of a 1 ยตF capacitor at a frequency of 60 Hz?
The capacitive reactance of a 1 µF capacitor at a frequency of 60 Hz is about 2700 ohms.
What two facctors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
What two factors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the alternating current passing through the capacitor and the capacitance value of the capacitor. Capacitive reactance (Xc) is inversely proportional to the frequency (f) and directly proportional to the capacitance (C), as calculated using the formula Xc = 1 / (2ฯfC).
How do you write out an equation used to find the inductive reactance ant the capacitive reactance?
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.
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.
Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
What is the reactance offered by a capacitor of freqency 100hz?
The reactance of a capacitor depends on its capacitanceand the frequency of the voltage across it.In general, the magnitude of capacitive reactance is . . .1 / (2pi x frequency x capacitance)At 100 Hz, that would be0.00159 / (capacitance) in Farads .
How can capacitive reactance be calculated?
it depends on capacitance and frequency, both inversely. Check your AC circuits textbook for the exact equation.
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
What does capacitive reactance oppose?
Inductive reactance.
What is relationships of capacitive reactance to resistance?
when ever current passing through any two parallel transmission line than due to the dieletric property of conductor some what capacitance effect will be generate between them that phenomina called as capitance reactance/////////////////// that symply we can called capitance reactance is measure of capitance The reactance of a capacitor is its resistance.
What is the value of capacitive reactance for DC?
Capacitive reactance Xc is equal to 1/2pi*f*C, wher f is input frequency and C is capacitance. Since for DC frequency is zero(no variation with time) Xc is infinite ideally and very very high practically.
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.
