This relationship shows us that when we connect capacitors in parallel then the equivalent capacitance of the circuit becomes sum of the capacitances of each individual capacitor in the connection. in other words, the total capacitance of the circuit increases.
Capacitors can be connected to each other in two ways. They can be connected in series and in parallel. We will see capacitors in parallel first. In this circuit capacitors are connected in parallel. Because, left hand sides of the capacitors are connected to the potential a, and right hand sides of the capacitors are connected to the potential b.
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:
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.
Systems including capacitors more than one has equivalent capacitance. Capacitors can be connected to each other in two ways. They can be connected in series and in parallel. We will see capacitors in parallel first. In this circuit capacitors are connected in parallel.
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,
