Figure 8.3.2 8.3. 2: (a) Three capacitors are connected in parallel. Each capacitor is connected directly to the battery. (b) The charge on the equivalent capacitor is the sum of the charges on the individual capacitors.
The complex impedance (Z) (real and imaginary, or resistance and reactance) of a capacitor and a resistor in parallel at a particular frequency can be calculated using the following formulas. Where: f is the Frequency in Hz. C is the Capacitance in Farads. R is the Resistance in Ohms. X C is the Capacitive Reactance in Ohms.
One important point to remember about parallel connected capacitor circuits, the total capacitance ( CT ) of any two or more capacitors connected together in parallel will always be GREATER than the value of the largest capacitor in the group as we are adding together values.
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,
These two basic combinations, series and parallel, can also be used as part of more complex connections. Figure 8.3.1 8.3. 1 illustrates a series combination of three capacitors, arranged in a row within the circuit. As for any capacitor, the capacitance of the combination is related to both charge and voltage:
Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge. To find the equivalent capacitance Cp C p of the parallel network, we note that the total charge Q stored by the network is the sum of all the individual charges:
