How do you take the Capacitance farads and voltage of a capacitor to determine its watt hours or amp hours?
1/(2 x 3.142 x f x C) where f is frequency of the supply & C is capacitance in farads.
for example mains frequency of 50Hz and capacitor of 1uF = reactance of 3182 ohms.
Watts = (volts) squared / reactance = 250 volts sq / 3182 = 19 watts
then multiply by time. Other factors involved but just approximation.

What do you measure capacitors in?
Capacitors are characterized by two values: their voltage, exceeding which will damage the capacitor (sometimes leading to a violent explosion), and their capacitance, as the name suggests. The voltage is expressed in volts. The capacitance is expressed in Farads. One (1) Farad is an amount of charge that makes the voltage across the capacitor terminals to rise by 1 Volt. If a 10mA current flows into the capacitor and it causes the capacitor's voltage to rise by 1V every second, the capacitor's capacitance is 10 milifarads. 1 Farad is a lot of charge, so for most applications, submultiples (microfarads and milifarads, mostly) are commonly used. A curious note: the more voltage a capacitor can handle, the (usually) bigger the size of it. At low voltages and low capacitance, the capacitance doesn't influence the size that much, though.
What is the SI unit of a capacitor?
Capacitors are measured in Farads or microfarads.
What does a capacitance of 0.00036 farads equal?
A capacitance of 0.00036 farads is equal to 360 microfarads.
What is the total capacitance of three 30 micro-farad capacitors connected in parallel?
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. In this case, with three 30 micro-farad capacitors connected in parallel, the total capacitance would be 3 times 30 micro-farads, which equals 90 micro-farads. This is because parallel connections provide multiple pathways for charge to flow, effectively increasing the total capacitance.
How long will it take to fully charge a capacitor in a series RC ciRCuit with a 6microfarad capacitor 2Kilohm resistor and 141 volt supply?
The time it takes to fully charge a capacitor depends on the capacitance and resistance of the circuit; the voltage is irrelevant. The equation you need is:t = 5RCwhere: t = time in seconds, R= resistance in ohms, and C =capacitance in farads.So you should now be able to calculate the time for yourself, but remember to convert the resistance into ohms and the capacitance into farads before you insert the figures into the equation.
How are the terms capacitor and capacitance related?
A capacitor is a device that stores electrical energy in an electric field between two conductive plates. Capacitance is a measure of a capacitor's ability to store charge per unit voltage. In other words, capacitance is the property that describes how much charge a capacitor can store for a given voltage.
What is the relation between the ac voltage frequency and the capacitor impedance?
A capacitor impedance is equivalent to 1/jwC, where j = i = imaginary number, w = frequency, and C = capacitance in Farads.
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 does NF on a capacitor mean?
While it is possible that the company producing the capacitor is using the NF as an identification tool, usually we would expect nF to specify the capacitance or value of the capacitor. For example, a capacitor with the value of 10nF ought to have a capacitance of about 10 nano Farads. This is equivalent to 10*10-9 Farads.
What is capacitance measured in?
. . is measured in farads or more usually microfarads or even picofarads. A capacitor has a capacitance of 1 farad when it has a voltage of 1 volt when there is 1 coulomb of charge on each plate. 1 coulomb is 1 amp flowing for 1 second.
How much energy is stored in each capacitor?
The amount of energy stored in a capacitor is determined by the formula: E 1/2 C V2, where E is the energy in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.

How many volts can a capacitor hold. what would be the formula for a capacitor that holds 100 volts?
The working voltage of a capacitor depends on the nature of the dielectric and its thickness. Most capacitors are marked on the case e.g. 500V wkg. or just 150V. Small components are colour coded; the code will tell you the capacitance, and the wkg voltage.
What is the SI unit of a capacitor?
Capacitors are measured in Farads or microfarads.
Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.
What is the largest capacitor available on the market and what are its specifications?
The largest capacitor available on the market is the Maxwell Technologies BCAP3000 P300 K04. It has a capacitance of 3000 farads, a voltage rating of 2.7 volts, and a maximum energy storage of 2700 joules.
As capacitance means the ability of storing charge then its unit should be Joule then why you called its unit farad?
I hear you saying that "joule" should be a unit of "ability"; that's pretty slippery."Joule" is a unit of energy. The capacitor does store energy.The energy stored in a capacitor is [ 1/2 C V2 ], measured in joules.' C ' is the capacitance, in farads.' V ' is the voltage across the capacitor, in volts.You can see that a larger capacitance (more farads), when charged to a smaller voltage,stores the same amount of energy. So the joules of energy stored in the capacitordepends on the capacitance and the voltage across it.The same energy can be stored in capacitors with different values of capacitance.In fact, the same capacitor can store different amountsof energy ... more or less joulesat different times.
