## Capacitors in series formulas

The capacitance of two capacitors in series is calculated using the following formula

$$\displaystyle C_{ges}=\frac{C_1· C_2}{C_1 + C_2}$$

To calculate a series capacitor for a given total capacitance and given C1, use the following formula

$$\displaystyle C_2=\frac{C_1· C_{ges}}{C_1 - C_{ges}}$$
