I am new to the forum and my maths is very poor, so please excuse me if this is posted in the wrong section.
I am trying to learn electrics and am reading about capacitance. Below is taken from the section that I am at.
Capacitors in series and parallel
Capacitors in parallel ADD together as C1 + C2 + C3 + ..... While capacitors in series REDUCE by:
1 / (1 / C1 + 1 / C2 + 1 / C3 + .....)
Consider three capacitors of 10, 22, and 47 uF respectively.
Added in parallel we get 10 + 22 + 47 = 79 uF. While in series we would get:
1 / (1 / 10 + 1 / 22 + 1 / 47) = 5.997 uF.
Note that the result is always LESS than the original lowest value.
The problem I am having is the formula below, I don't understand it and how to arrive at the answer given. Google presented 1 / (1 / 10 + 1 / 22 + 1 / 47) = 5.997 uF
as 1 / ((1 / 10) + (1 / 22) + (1 / 47)) = 5.99767981 but I still do not understand it.
Maybe someone would be kind as to break it down and explain how it is calculated as I have tried various methods and can't get anywhere near the correct answer.
I feel so stupid as I have a feeling it is simple but I am determined to learn so that is the first obstacle tackled I guess.
