The job of a capacitor is to store charge onto its plates. The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors.
- The surface area, A of the two conductive plates which make up the capacitor, the larger the area the greater the capacitance.
- The distance, d between the two plates, the smaller the distance the greater the capacitance.
- The type of material which separates the two plates called the "dielectric", the higher the permittivity of the dielectric the greater the capacitance.

What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
How long can a capacitor hold a charge for?
Depends upon the capacitance. The time of holding charge can analyse by transient analysis.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.
Why does capacitance increase when the distance between the plates of a capacitor is increased?
you have it reversed. capacitance increases with decrease in distance of plates.
What two factors determine the capacitive reactance of a capacitor?
capacitive reactance is inversely proportional to the capacitance of the capacitor and frequency of the AC line reactance (in ohms) = 1/(capacitance * frequency)
How are the terms capacitor and capacitance related?
Capacitor is the name of the device and capacitance is a measure of farads in the capacitor. Capacitance is the capacity for storing charge in the capacitor as measured in farads, micro farads or millifarads.
What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?
capacitance will tend to zero
What means by the name capacitance of a capacitor?
The capacitor is an electronic device. Capacitance is the energy stored within this device.
What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
What is a capacitor analyzer designed to read?
Capacitor voltage
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.
What is the ratio of capacitance of capacitors?
ratio of capacitance of capacitor is given by charge\potential
How long can a capacitor hold a charge for?
Depends upon the capacitance. The time of holding charge can analyse by transient analysis.
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 .
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
What is the difference betbeen capacitor and condensor?
A: Both nomenclature are indicator of capacitance it can be used both ways. However the predominate usage is capacitor since it resemble capacitance
