Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other.
AI Customer ServiceSo, if both capacitors (small and large) have the same capacitance then one will (more than likely) work up to a larger voltage. A capacitor that is polarized (e.g. electrolytic

AI Customer ServiceThe charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage. Charging the capacitor stores energy in the electric field between the capacitor plates. The rate of charging is typically described in terms of a time constant RC. C = μF, RC = s = time constant. just after the switch is closed.
From the above discussion, we can conclude that during charging of a capacitor, the charge and voltage across the capacitor increases exponentially, while the charging current decreases. A charged capacitor stores electrical energy in the form of electrostatic charge in the dielectric medium between the plates of the capacitor.
Capacitor Charging Definition: Charging a capacitor means connecting it to a voltage source, causing its voltage to rise until it matches the source voltage. Initial Current: When first connected, the current is determined by the source voltage and the resistor (V/R).
A capacitor will always charge up to its rated charge, if fed current for the needed time. However, a capacitor will only charge up to its rated voltage if fed that voltage directly. A rule of thumb is to charge a capacitor to a voltage below its voltage rating.
A rule of thumb is to charge a capacitor to a voltage below its voltage rating. If you feed voltage to a capacitor which is below the capacitor's voltage rating, it will charge up to that voltage, safely, without any problem. If you feed voltage greater than the capacitor's voltage rating, then this is a dangerous thing.
The time it takes for a capacitor to charge to 63% of the voltage that is charging it is equal to one time constant. After 2 time constants, the capacitor charges to 86.3% of the supply voltage. After 3 time constants, the capacitor charges to 94.93% of the supply voltage. After 4 time constants, a capacitor charges to 98.12% of the supply voltage.
