How do you calculate the value of two capacitors conected together?

If the internal capacitors are separate, I mean that there are 4 terminals, a separate positive and negative for each internal cap then you can connect them in two ways. If you connect them in parallel (positive to positive and negative to negative) you just add the values together, so if each is 100UF they total 200Uf and the voltage you can apply is whatever is rated on the body. If you want to increase the voltage so you can apply higher voltage you connect them in series, one of the negatives connects to the others positive and the remaining inputs are connected to the circuit (and if each is equal in value) you divide by two so they would only be 50UF in capacitance but the total voltage you can apply is double the rated level on the body. If the caps are of different values it gets more complicated, you have to calculate the C total buy using the following formula: 1/C total = 1/C1 + 1/C2. Then the voltage dropped across each cap is proportional to the values you calculated above. Remember, the total voltage will be dropped across the caps proportionally so if the caps are rated at 50V for example and they are not equal values, you can't connect them up to 100V because the larger of the caps will have more than 50V across it because of the mis-matched value of each.

∙ 7y agoThe total value for capacitors in series equals the reciprocal of the sum of the reciprocals of the individual capacitances. The number of capacitors connected together in series will always be less than the value of the smallest capacitor in the series. It is the same equation that is used for resistances in parallel.

What if four capacitors of equal value are in series?
The total capacitance is one fourth of the capacitance of the individual capacitors. The voltage rating is four times the voltage rating of the individual capacitors (however to prevent uneven charging of the four capacitors and failure of one or more they must be paralleled with a voltage divider composed of four equal value resistors).
Why does generally capacitors are in pico or nano farads not in kilo or mega farads?
Large value capacitors are difficult to make (large value inductors are even harder to make) and take up large volumes of space. One farad capacitors are available in electrolytics, but are about the size of soup cans. If they were made, kilo & mega farad electrolytic capacitors would have volumes of roughly a thousand & a million soup cans respectively! Nonelectrolytic capacitors would be far larger!!!
What is difference between variable capacitor and fixed capacitor?
variable capacitors are those capacitors which can be intially or randomly canged by the user for example radio tunning.whereas fixed capacitors are those whose value is fixed and can't be changed. sohaib
Why aren't inductors used in timer circuits?
Mostly because large value capacitors are less expensive and smaller than large value inductors.
How the capacitor valve calculate for a for a load?
I assume that you are asking how to calculate the 'value' of a capacitor? Well, it depends what it is used for. If, for example, it is used to improve the power factor of a load, then it is first necessary to determine what the load's existing reactive power is; then, you need to know what reactive power is necessary with the power factor at its desired value; finally you need to difference between the actual and the desired values of reactive power -and this will be the necessary value for the capacitor. Power factor correction capacitors are rated in reactive volt amperes, not farads.
What is the total capacitance of a circuit with three capacitors connected in series with the following values C1 015 fd C2 015 fd and C3 015?
It looks like all three of your capacitors have the same value. So the effective capacitance when they're all conected in series is 1/3 of that value = 0.005 fd.
Physics numerical four capacitors each of 2micro farad are connected in such a way that the total capacitance is also 2 micro farad show what combination gives this value?
In order to connect four 2 microfarad capacitors such that the total capacitance is still 2 microfarads, connect two pairs of capacitors in series, and then connect the pairs in parallel. It does not matter, since all four capacitors are equal in value, if the center point is connected together or not.
How do you calculate capacitanse of parallel capacitor?
A: All capacitors are added in value for a total value. In series each capacitor value is divided into '1' and the fraction value is added to the next fraction and so on While in parallel the value increases in series the value decreases with each addition

Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.

What is the formula for calculating self capacitance of an inductor when the value of capacitance and frequency for two capacitors is given?
You seem to be mixing up your terminology. There is no such thing as 'self-capacitance of an inductor'! If you know the frequency and equivalent capacitance for two capacitors, then you can find the equivalent capacitive reactance of the capacitors, but that's not what you seem to be asking! I suggest you rephrase the question.
Does 001 farad of capacitor have polarity?
Only electrolytic capacitors (tantalum capacitors are a type of electrolytic capacitor) are polarized.0.001 farad = 1000 microfaradThis is a value that is too large for any practical capacitor except an electrolytic, so yes it will be polarized.
