6.1.2: Capacitance and Capacitors
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.
Understanding DC Circuit Capacitor Behavior
When the capacitor voltage equals the battery voltage, there is no potential difference, the current stops flowing, and the capacitor is fully charged. If the voltage increases, further migration of electrons from the positive to negative plate results in a greater charge and a higher voltage across the capacitor.
