Can you replace a capacitor of two different sizes?
Not sure what you are asking.There are two formulae for working out equivalent capacitance:Two capacitors in parallelThe equivalent single capacitance is the sum of the two capacitors: Ce = C1 + C2Two capacitors in seriesThe equivalent single capacitance is the reciprocal of the sum of the reciprocals of the two capacitors: 1/Ce = 1/C1 + 1/C2⇒ Ce = C1C2/(C1+C2)So you can replace two capacitors by a single one, or a single one by two.
What is the inverse of capacitance?
The reciprocal of capacitance is elastance. This is perhaps more convenient for circuit analysis than capacitance. In a circuit, a capacitor can be neglected if the elastance is set to zero. In the same way, a resistor/inductor can be ignored if its resistance/inductance is set to zero.
What is the mutual capacitance of two spheres?
The capacitance of two spheres can be calculated using the 'method of images' repeatedly. This gives the result as a fast converging series. Details: http://www.iue.tuwien.ac.at/phd/wasshuber/node77.html
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
What is eqivalent ratio?
an eqivalent ratio is an ratio that is equal or you can simplfiy it
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
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.
What is the equivalence capacitance of combinations?
The equivalence capacitance of capacitors in series is calculated using the formula: ( \frac{1}{{C_{eq}}} = \frac{1}{{C_1}} + \frac{1}{{C_2}} + \dots ), where ( C_{eq} ) is the total capacitance. For capacitors in parallel, the total capacitance is the sum of the individual capacitances: ( C_{eq} = C_1 + C_2 + \dots ).
What happens to capacitors that are connected in series?
When capacitors are connected in series, their total capacitance decreases. This is because the total capacitance is inversely proportional to the sum of the reciprocals of the individual capacitances. The voltage across each capacitor remains the same.
What is capacitor derive an expression for total capacitance when three capacitors are connected in parallel?
capacitance C=C1+C2+C3
When you put two 10 µF capacitors in parallel the equivalent capacitance would be?
With capacitors in parallel you can just add the microfarads.
Modern capacitors which have high capacitance in small size use a dielectric of?
mylar
What is the capacitance of 15 microfarad and 15 microfarad capacitors in parallel?
30 microfarads
What are centimeters capacitors?
It unit of capacitance is the centimeter, or one esu per statvolt.
Modern capacitors which have high capacitance in small size use a dielectric?
Ceramic
How capacitors are arranged?
Capacitors are one of the standard components in electronic circuits. Moreover, complicated combinations of capacitors often occur in practical circuits. It is, therefore, useful to have a set of rules for finding the equivalent capacitance of some general arrangement of capacitors. It turns out that we can always find the equivalent capacitance by repeated application oftwosimple rules. These rules related to capacitors connected in series and 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).
