If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse proportion.
Two parallel-plate capacitors, 6.0 μF each, are connected in parallel to a 10 Vbattery. One of the capacitors is then squeezed so that its plate separation is 50.0% of its initial value. Because of the squeezing, (a) How much additional charge is transferred to the ...

Given the specific geometry of a capacitor, one can compute the capacitance directly from Gauss's law. However, in most practical situations, the exact geometry is not specified. Rather, one is given the capacitance of several …
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. As we''ve just seen, an increase in plate area, with all other factors unchanged, results in increased capacitance.
Since Kirchhoff''s voltage law applies to this and every series connected circuit, the total sum of the individual voltage drops will be equal in value to the supply voltage, V S.Then 8.16 + 3.84 = 12V.Note also that if the capacitor values are …

When capacitors are connected in parallel, their capacitance will simply add together to give you the total capacitance. Thus, connecting capacitors in parallel allows you to achieve a greater capacitance than you could with a single capacitor since each one will be able to store more energy.
