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.
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:
Tuning Circuits: Capacitors in series and parallel combinations are used to tune circuits to specific frequencies, as seen in radio receivers. Power Supply Smoothing: Capacitors in parallel are often used in power supplies to smooth out voltage fluctuations.
A positive charge accumulates on one plate, while an equal amount of negative charge accumulates on the opposite plate. The amount of charge stored depends on the applied voltage and the capacitance of the capacitor. What factors affect the capacitance of a parallel plate capacitor?
The dielectric material in a parallel plate capacitor increases its capacitance by reducing the electric field strength for a given amount of charge. This allows more charge to be stored on the plates for a given voltage. Dielectric materials also provide insulation, preventing the plates from coming into direct contact and shorting out.
which means that the equivalent capacitance of the parallel connection of capacitors is equal to the sum of the individual capacitances. This result is intuitive as well - the capacitors in parallel can be regarded as a single capacitor whose plate area is equal to the sum of plate areas of individual capacitors.
