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.
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.
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.
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.
Hence, when two capacitors are connected in series, their equivalent capacitance can be directly calculated by multiplying the two capacitances and then dividing by their sum. Let’s consider another special case, when two capacitors have the same capacitance, i.e., C 1 = C 2 = C. In this case, we get,
Because the capacitors share one common path, the charge across their plates is always the same. Therefore, in a series circuit, the same charge will flow through each capacitor, resulting in the same voltage drop. In addition, the capacitors in a series connection have the same reactance and will store the same amount of electrical charge.
