Formula: Series Circuit of Capacitors

Series connection of two capacitors

Total charge

Unit
Electric charge is equal on all capacitors connected in series.

For example, if the charge \( \class{red}{Q_1} = 0.2 \, \mathrm{C} \) is stored on the first capacitor, then the same amount of charge is also stored on all other capacitors: $$ \class{red}{Q} ~=~ \class{red}{Q_1} ~=~ \class{red}{Q_2} ~=~ \class{red}{Q_3} ~=~ 0.2 \, \mathrm{C} $$

Individual charges

Unit
  • \(\class{red}{Q_1}\) is the charge on the first capacitor.
  • \( \class{red}{Q_2}\) is the charge on the second capacitor.
  • \( \class{red}{Q_3}\) is the charge on the third capacitor.
  • \( \class{red}{Q_n}\) is the charge on the \(n\)th capacitor.
