When capacitors are connected in series, the capacitor plates that are closest to the voltage source terminals are charged directly. The capacitor plates in between are only charged by the outer plates. In a series circuit, the total voltage drop equals the applied voltage, and the current through every element is the same.
However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
Why it’s important: Capacitors in series reduce the overall capacitance of the system. This can be used to engineer a specific capacitance using commonly manufactured components. Capacitance is the ratio of the total charge stored in the capacitor to the voltage drop across it:
The capacitor plates in between are only charged by the outer plates. In a series circuit, the total voltage drop equals the applied voltage, and the current through every element is the same. The charge on every capacitor plate is determined by the charge on the outermost plates and is limited by the total equivalent capacitance of the circuit.
When this block is connected to a voltage source, each capacitor in the block stores an equal amount of charge, which means that the total amount of charge is evenly distributed across all of the capacitors, regardless of their capacitance. The amount of charge stored at each capacitor equals:
