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 is the relationship between potential difference and capacitance in a capacitor?

The relationship between potential difference and capacitance in a capacitor is that the potential difference across a capacitor is directly proportional to its capacitance. This means that as the capacitance of a capacitor increases, the potential difference across it also increases, and vice versa.


What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?

capacitance will tend to zero


Suppose a parallel plate capacitor (with capacitance) is connected to a battery, what is the relationship between the charge stored on the capacitor and the potential difference across its plates?

The relationship between the charge stored on a capacitor and the potential difference across its plates is that the charge stored on the capacitor is directly proportional to the potential difference across its plates. This relationship is described by the formula Q CV, where Q is the charge stored on the capacitor, C is the capacitance of the capacitor, and V is the potential difference across the plates.


What is the ratio between the charge on either plates of capacitor and the potential difference between the plate?

The ratio between the charge on either plate of a capacitor (Q) and the potential difference (V) across the plates is given by the capacitance (C) of the capacitor, expressed as ( C = \frac{Q}{V} ). This means that the capacitance is a measure of how much charge a capacitor can store per unit of voltage applied. Therefore, the ratio ( \frac{Q}{V} ) is constant for a given capacitor and is equal to its capacitance.


What is the formula for calculating the potential difference in a capacitor based on its capacitance and the charge stored on its plates?

The formula for calculating the potential difference in a capacitor is V Q/C, where V is the potential difference, Q is the charge stored on the plates, and C is the capacitance of the capacitor.

How is the change of potential difference across the capacitor determined?

The change in potential difference across a capacitor is determined by the amount of charge stored on the capacitor and the capacitance of the capacitor. The relationship is given by V = Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the 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


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.
