The maximum amount of voltage that can be applied to the capacitor without damage to its dielectric material is generally given in the data sheets as: WV, (working voltage) or as WV DC, (DC working voltage).

When a capacitor is connected to a voltage source, it charges up, and its voltage increases gradually until it reaches the same voltage as the applied source. The rate of voltage increase depends on the time constant of the charging circuit, which is determined by the capacitance and resistance in the circuit.
The voltage across a capacitor can be equal to the voltage of the battery or voltage source to which it is connected during the charging process. However, in steady-state conditions or when the capacitor is fully charged or fully discharged, the voltage across the capacitor remains constant and equal to the applied voltage. 15.
However, in the long term, the voltage across the capacitor will remain constant. When a capacitor is first connected to a voltage source, the voltage across the capacitor is initially zero. As the capacitor begins to charge, the voltage across the capacitor starts to increase until it reaches the same voltage as the voltage source.
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. Image used courtesy of Adobe Stock
The rate of voltage increase depends on the time constant of the charging circuit, which is the product of the capacitance and resistance in the circuit. During discharging, the voltage across the capacitor decreases exponentially until it becomes fully discharged, reaching zero volts.
Yes, capacitors can divide voltage in a circuit when they are connected in series. In a series configuration, the total voltage is divided among the individual capacitors based on their capacitance values. The voltage across each capacitor in series depends on the charge stored on it, which is determined by its capacitance. 13.

An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so it is a displacement current that the ammeter records.
