Capacitor in Series

Capacitor in Series

Capacitor in Series

As can be seen in the picture, the plate distances add up when capacitors are connected in series. This means that the total capacitance must be reduced:

1       =   1   +  1  +    1   +  …
CEq      C1      C2      C3

Capacitor in Parallel

Capacitor in Parallel

Capacitor in Parallel

As can be seen in the picture, when capacitors are connected in parallel, the plate surfaces add up. Therefor the total capacitance increases:

CEq  =  C1 + C2 + C3 + …


Exercises
