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 in a DC circuit, the voltage drop across individual capacitors at and immediately after the initial charging period is inversely proportional to the individual capacitance of each capacitor. But afterwards, this begins to change due to leakage current.
Increased Voltage Rating: By combining capacitors in series, you can effectively achieve higher voltage ratings for your circuit. Voltage Division: Series capacitors facilitate voltage division, enabling different voltage drops across each capacitor.
The total capacitance ( C T ) of the series connected capacitors is always less than the value of the smallest capacitor in the series connection. If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure.
Deciding between series and parallel capacitor configurations depends on the specific requirements of your circuit. If you need to maintain the same voltage rating while increasing capacitance, parallel connection is suitable. On the other hand, if you aim to boost voltage ratings without altering capacitance, series connection is the way to go.
In a series connection, capacitors are connected end-to-end, forming a single path for the flow of current. To calculate the total capacitance in a series circuit, you need to use the reciprocal formula. Simply put, you take the reciprocal of each capacitor’s value and add them together. The equivalent capacitance (C) can be calculated as:
