This tool calculates the total capacitance for any number of capacitors connected in series.

**Formula**

When capacitors are connected in series, the total or equivalent capacitance (**C _{total}â€‹**) is less than any individual capacitor’s capacitance in the circuit.

The formula to calculate the total capacitance of n capacitors connected in series is given by the reciprocal of the sum of the reciprocals of their individual capacitances:

**1/C _{totalâ€‹} = 1/C_{1}â€‹â€‹+ 1/C_{2}â€‹ â€‹+ â‹¯ +C_{n}â€‹â€‹**

Or for two capacitors in series, it simplifies to:

**1/C _{totalâ€‹} = 1/C_{1}â€‹â€‹+ 1/C_{2}â€‹ â€‹â€‹**

And **C _{total}** can be found by taking the reciprocal of the sum:

**C _{total} = C_{1}C_{2}/(C_{1}+C_{2})**

**Example Calculation**

Two capacitors with values 1 ÂµF and 3 ÂµF in series gives a total series capacitance value of 0.75 ÂµF.
