What is the difference between capacitive reactance and capacitance?

∙ 10y ago
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.
Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.

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.
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 difference between static var compensator and static var cenerator?
there is no such thing as static var cenerator but if you meant static var generator then the difference is the same. it is one in the same thing, a combination or inductance and capitance to generate either reactive inductance or capacitive reactance.
What is Pure Resistive?
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
When the distance between the plates of a capacitor decreases what happens to the capacitance?
-- it has larger capacitance -- it can store more charge at the same voltage -- it can store more energy at the same voltage -- it has lower capacitive reactance at any given frequency -- in combination with a given resistor, the cut-off frequency of a high- or low-pass filter is lower -- in combination with a given inductor, their resonant frequency is lower

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 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

How does touch screen capacitive works?
touch screen capacitive works by the capacitance differential between the screen and your finger wherever there is difference in capacitance on the screen is where you are touching and the screen knows what function you are trying to do depending on what is displayed on the screen.
What is the relationship between capacitance and frequency?
This is a very broad generalization, but in general, increasing the value of one or more capacitors in an electronic circuit will decrease the resonant frequency of one or more sections of the circuit.
WHAT ARE THE APPLICATION OF CAPACITIVE TRANSDUCERS?
Capacitive sensors are used mainly to detect proximity, usually that of people. The operating principle is that the capacitance of the capacitor varies as material comes between the two plates of the capacitor, and you can determine the presence of something via the measurement of the capacitance.
What is meant by resonance in LCR circuit?
a circuit in which inductance L,capacitance C and resistance R are connected in series and the circuit admits maximumum current corresponding to a given frequency of a.c.Another AnswerIn the case of a series circuit, resonance occurs when its inductive reactance is exactly equal to its capacitive reactance. As the vector sum of these two quantities will then be zero, the only opposition to current will be resistance and, so, maximum current will flow through the circuit when resonance occurs. ALL circuits can be made to resonate at what is called their 'resonant frequency' because, as frequency increases, the inductive reactance increases but capacitive reactance falls -so, at some point the two will equal each other, and resonance will occur.In my view resonance means - the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
What is the difference between capacitance and capacity?
Capacitance is quite literally the capacity to hold charge at a given potential difference.
What is the difference between static var compensator and static var cenerator?
there is no such thing as static var cenerator but if you meant static var generator then the difference is the same. it is one in the same thing, a combination or inductance and capitance to generate either reactive inductance or capacitive reactance.

A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
What is impedance diagram?
An impedance diagram (sometimes called an impedance triangle) results when a series circuit's voltage phasor diagram is divided throughout by its reference phase (current) -this results in resistance (=VR/I), inductive reactance (=VL/I), capacitive reactance (=VC/I) and impedance (=V/I) andillustrates the Pythagorean relationship between the circuit's impedance, reactance, and resistance.
