Here’s how to calculate the total amount of capacitance for Capacitors in Series and Parallel.
Let’s say we’re starting out with two capacitors, one 4 uF and one that is 6 uF.
Here is the formula for calculating their value if they’re in Series.
Entering the example values into the equation yields:
C_{Total} = \dfrac{1} { \dfrac{1}{4\ uF } + \dfrac{1}{6\ uF}} = \dfrac{1} {0.25 + 0.167 } = 2.4\ uF
If they’re in parallel the formula would be:
in which case 4uF + 6uF the answer would be 10uF.
