When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors'' capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.

Note that in a parallel network of capacitors, the equivalent capacitance is always larger than any of the individual capacitances in the network. Capacitor networks are usually some combination of series and parallel connections, as shown in Figure (PageIndex{3}). To find the net capacitance of such combinations, we identify parts that contain only series or only parallel connections,
Capacitive Reactance in Parallel. When capacitors are connected in parallel, the total reactance of the capacitors, X CT, is found in the same manner that total resistance, R T, is determined in a parallel resistive circuit.

In other words, the solid curve shown represents the varying reactance characteristics of 0.1 μF capacitor only. X C in Series and Parallel. Series and parallel combinations of capacitive reactance are treated in the same manner as inductive reactance.

For Parallel Capacitors When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors’ capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.
Capacitive reactance opposes the flow of current in a circuit and its value depends on the frequency of the applied voltage and the capacitance rating of the capacitor. The reactance is calculated to determine the impedance of a circuit, which is a measure of the total opposition to the flow of current in the circuit.
As stated earlier, this changing opposition of a capacitor is called capacitive reactance and is inversely related to the source frequency. Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor. where 2π =6.28. The symbol for reactance is X.
Capacitance and capacitive reactance both changes when multiple capacitors are introduced to the existing circuit. It changes based on how they are connected i.e. series or parallel. An equivalent capacitance can be calculated when multiple capacitors are connected in series or parallel to simplify the given circuit.
