Series Capacitance

The reciprocal of the total capacitance of n capacitors in series equals the sum of the reciprocals of each capacitor.

frac{1}{C_{total}}=frac{1}{C_{1}}+frac{1}{C_{2}}+frac{1}{C_{n}}

frac{1}{C_{1}}=frac{1}{C_{total}}-frac{1}{C_{2}}-frac{1}{C_{n}}

frac{1}{C_{2}}=frac{1}{C_{total}}-frac{1}{C_{1}}-frac{1}{C_{n}}

etc.
