capacitordivision

Capacitor division is a circuit configuration where two or more capacitors are connected in series. Similar to a resistor divider, a voltage applied across the series combination of capacitors will be distributed among them. The voltage across each capacitor is inversely proportional to its capacitance. The total capacitance of capacitors connected in series is calculated by the reciprocal of the sum of the reciprocals of individual capacitances. This means that the total capacitance is always less than the smallest individual capacitance. This principle is utilized in applications where a voltage needs to be stepped down or when a specific voltage distribution across multiple capacitors is required. For instance, in some power supply circuits or signal processing applications, capacitor dividers can be used to achieve desired voltage levels or to filter out specific frequencies. The voltage division ratio between two capacitors in series, C1 and C2, with voltages V1 and V2 across them respectively, is given by V1/V2 = C2/C1. The sum of the voltages across each capacitor equals the total applied voltage.
