How To Calculate Capacitors In Series And Parallel

Capacitors in Parallel

When capacitors are connected across each other (side by side) this is called a parallel connection. This is shown below. how_to_calculate_capacitors_in_series_and_parallel_1 To calculate the total overall capacitance of a number of capacitors connected in this way you add up the individual capacitances using the following formula: CTotal = C1 + C2 + C3 and so on Example: To calculate the total capacitance for these three capacitors in parallel. how_to_calculate_capacitors_in_series_and_parallel_2 CTotal = C1 + C2 + C3 = 10F + 22F + 47F = 79F
 

Task 1:

Calculate the total capacitance of the following capacitors in parallel. how_to_calculate_capacitors_in_series_and_parallel_3

Capacitors in Series

When capacitors are connected one after each other this is called connecting in series. This is shown below. how_to_calculate_capacitors_in_series_and_parallel_4 To calculate the total overall capacitance of two capacitors connected in this way you can use the following formula:
Ctotal =  C1 x C2  and so on
 C1 + C2
Example: To calculate the total capacitance for these two capacitors in series. how_to_calculate_capacitors_in_series_and_parallel_5
 

Task 2:

Calculate the total capacitance of the following capacitors in series. how_to_calculate_capacitors_in_series_and_parallel_6

Three or more capacitors in series

how_to_calculate_capacitors_in_series_and_parallel_7 To calculate the total overall capacitance of three or more capacitors connected in this way you can use the following formula: how_to_calculate_capacitors_in_series_and_parallel_8 and so on. Example: To calculate the total capacitance for these three capacitors in series. how_to_calculate_capacitors_in_series_and_parallel_9
 

Task 3:

Calculate the total capacitance of the following capacitors in series. how_to_calculate_capacitors_in_series_and_parallel_10

Task 1

1 = 232.2F 2 = 169.0F 3 = 7.0F

Task 2

1 = 2.48F 2 = 14.99F 3 = 4.11F

Task 3

1 = 3.33F 2 = 1.167F 3 = 0.35F Note The capacitor values in this worksheet have been kept high (close to or greater than one). This is to simplify the learning experience. In reality typical capacitor values are much smaller than one.   Download a pdf version of this page here. pdf_icon.gif Learn more about the author If you found this article helpful and you would like to receive product updates and free electronic resources from us then sign up here.

Hi, we don't have a guide showing this at the moment, but it is something we should add. You have guessed correctly how to calculate the total capacitance for your circuit. I hope this helped.

Do you have any tasks worked out with similar images as shown above? I am trying to figure out this same problem. I have two capacitors parallel to each other but also in a series with one other capacitor. Would I add the two in parallel and then use that number in the equation for the series? Any advice is helpful thank you!!

Hi Emmanuel, You can work out the capacitance of each of the areas individually and then work out how to find the total capacitance, the method would be determined by how the different areas are arranged in relation to each other. They may be in series with each other or in parallel. I hope this helps.

How do I work out capacitors connected in both parallel and series

Hi Kean, there is still one more step of your calculation left to do, you need to divide 1 by 3 and then you will have your answer for C total. Hope this helps.

The formula for series capacitance does not work for 1F. If you add 1+1+1 you get 3F instead of .333F. Please explain.

Very very helpful site I like it.. Being a student of class 10th I understood it to how to solve the question of series and parallel combinations of conductors..

This may be something that we produce a resource for at some point but for now, try google as there is already a lot of information on this online.

Hi Douglas, The calculation examples will work regardless of the values of the individual capacitors.

Hi, It appears that your examples deal only in capacitors of varying capacitance. It would be useful to include examples of identical capacitors connected in series and parallel. Series Connected Identical Capacitors….. Total Capacitance= Nominated Capacitance divided by Total number of Capacitors. EG.. 3000 Farad ÷(X5 in series), …3000F/5=600F. Parrallel Connected Identical Capacitors…… Total Capacitance=Nominated Capacitance Times Total Number of Capacitors………. 3000Farad X (X5 in parallel)…3000FX5=15,000F Does away with all the “Long Division Nonsense”

Hi, The voltage would remain the same. Rob

Haruna Ibrahim

Haruna Ibrahim

The explanation is clear, but what about the working voltage of two capacitors in parallel? Does it remains the same or individual capacitor voltage rating is added up. Suppose both capacitors are the same working voltage rating

i think task 3 is suppose to be 1.167F not 1.67F
