2 天之前· Consider two capacitors with capacitances of 6 μF and 3 μF connected in parallel. Using the capacitors in parallel formula: C eq = 6 μF + 3 μF = 9 μF. This simple addition demonstrates how combining capacitors in parallel effectively increases the total capacitance, which is beneficial in applications requiring higher energy storage.
Capacitors, like other electrical elements, can be connected to other elements either in series or in parallel. Sometimes it is useful to connect several capacitors in parallel in order to make a functional block such as the one in the figure. In such cases, it is important to know the equivalent capacitance of the parallel connection block.
Well, just replace C1 in the circuit above with a 100 µF and a 47 µF capacitor in parallel, and you end up with a total capacitance of 147 µF. Another typical place where you’ll see capacitors connected in parallel is with microcontroller circuits. Microcontroller chips often have several power pins.
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.
One example are DC supplies which sometimes use several parallel capacitors in order to better filter the output signal and eliminate the AC ripple. By using this approach, it is possible to use smaller capacitors that have superior ripple characteristics while obtaining higher capacitance values.
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:
Look for Common Points: If two or more capacitors share a common point on both their positive and negative terminals, they are in parallel. Consider the Voltage and Charge: In a series connection, the voltage is divided among the capacitors. In a parallel connection, the voltage is the same across all capacitors.
