Capacitors In Series

Capacitors are said to be connected together “in series” when they are effectively “daisy chained” together in a single line. The charging current ( IC ) flowing through the capacitors is the same for all capacitors as it only has one path to follow. Then, Capacitors in Series all have the same current so each capacitor stores the same amount of charge regardless of its capacitance. Capacitors connected together in series all have the same amount of charge.

1/CT = 1/C1 + 1/C2 + 1/C3 +…
VS = VC1 + VC2 + VC3 + ...
Q = VS CT = V1 C1 = V2 C3 = V3 C3 = ...
IT = IC1 = IC2 = IC3 = ...
