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 the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
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.
How does the capacitance of parallel plate capacitor vary with separation between plates of it?
capacitance is inversely proportional to the separation between the platesproof :-electric field is ;- k/E0where k- surface charge density of the plateand potential difference is given by kl/E0and, capacitance by C=Q/Vso, capacitance is inversely proportional to separation between the plates
How much power in one farad?
Theæ definition of farad is as follows; SI unit of capacitance, formally defined to be the capacitance of a capacitor between the plates of whichæthere appears a potential difference of one volt when it is charged by a quantity of electricity equal to one coulomb.
What does the farad rating mean in capacitors?
The rating or 'size' of a capacitor, called its "capacitance", is related the amount of charge the capacitor can store, to the amount of energy it holds when it stores some charge, and to the opposition of the capacitor to the apparent flow of alternating current through it. If a capacitor has a capacitance of 1 farad, then -- One coulomb of charge stripped off of one plate and added to the other plate produces 1 volt of potential difference between the plates. -- The energy stored in the capacitor is 1/2 the square of the voltage across it. -- Its impedance is (0.159 divided by the frequency) ohms. The farad is an enormous capacitance. A typical capacitor used in a 'lumped' circuit ... the kind of construction where you would buy a capacitor and solder it in ... has a capacitance in the range of maybe 10 picofarads (trillionths of a farad) to maybe 100 microfarads (millionths of a farad).
What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?
capacitance will tend to zero
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
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
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.
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.
How does the capacitance of parallel plate capacitor vary with separation between plates of it?

What is D in capacitance measurement?
You think probable to the distance between the plates of the capacitor.
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 an importance of capacitance?
capacitor is a device to store charge .it is based on the concept that when the potential of the capacitor is decreased it can gain some more charge so Q = CV where V is potential and Q is the charge stored then C is the capacitance. capacitance is the ability of the capacitor to store charge. expression for capacitance is C=ɛA/d where ɛis permittivity and A is area of capacitor plates ,d is plate separation.
What is a capacitor analyzer designed to read?
Capacitor voltage
What is the ratio of capacitance of capacitors?
ratio of capacitance of capacitor is given by charge\potential
What are the methods to find capacitance of a capacitor?
You could measure it with a Capacitance meter. Or you could use the formula:In a parallel plate capacitor, capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +q and −q, and V gives the voltage between the plates, then the capacitance C is given byFor further info on the total value of capacitance in series or parallel, Google it.
