Series capacitance refers to connecting multiple capacitors together to form a capacitor series circuit. In the series circuit, the anode and cathode of the capacitor are connected in turn, and the total capacitance value is equal to the reciprocal of the sum of the reciprocal values of all capacitors. That is, if there are n capacitance values of C 1, C2, ..., Cn, the total capacitance value is1(1/c1/C2+...+1/cn).
Parallel capacitor refers to connecting multiple capacitors together at the same time to form a capacitor parallel circuit. In the parallel circuit, the anode and cathode of the capacitor are connected respectively, and the total capacitance value is equal to the sum of all capacitor capacitance values. That is to say, if there are n capacitors whose values are C 1, C2, ..., Cn, and the total capacitance value is C 1+C2+...+Cn, the voltage is evenly distributed on each capacitor.
To sum up, the difference between series capacitor and parallel capacitor lies in the connection mode and the calculation method of total capacitance. Series capacitance is to connect a plurality of capacitors together, and the total capacitance value is equal to the reciprocal of the sum of the reciprocal values of all capacitors; Parallel capacitor is to connect multiple capacitors together at the same time, and the total capacitance value is equal to the sum of the capacitance values of all capacitors.
