When capacitors are connected in series, their individual capacitance values contribute to the total equivalent capacitance. The series connection is achieved when the positive plate of one capacitor is connected to the negative plate of the subsequent capacitor. This forms a continuous path for current flow, creating a series circuit.
When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
Also for capacitors connected in series, all the series connected capacitors will have the same charging current flowing through them as iT = i1 = i2 = i3 etc. Two or more capacitors in series will always have equal amounts of coulomb charge across their plates.
With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
Combining capacitors in series reduces the total capacitance, and isn't very common, but what are some possible uses for it? It shouldn't be used to increase the voltage rating, for instance, since you can't guarantee that the middle will be at half the DC voltage of the total, without using bleeder resistors.
The capacitance doesn't increase in series; it decreases. Capacitors in parallel are capacitors that are connected with the two electrodes in a common plane, meaning that the positive electrodes of the capacitors are all connected together and the negative electrodes of the capacitors are connected together.
Capacitors have a maximum voltage they can take before the dielectric (or vacuum) inside of them breaks down and starts conducting. Thus, if you need to have a …
