How a capacitor is charged?
As discussed earlier, the charging of a capacitor is the process of storing energy in the form electrostatic charge in the dielectric medium of the capacitor. Consider an uncharged capacitor having a capacitance of C farad. This capacitor is connected to a dc voltage source of V volts through a resistor R and a switch S as shown in Figure-1.

What is capacitance value of a capacitor?
The ability of a capacitor to store maximum charge (Q) on its metal plates is called its capacitance value (C).

The expressions for charge, capacitance and voltage are given below.
How do capacitors store electrical charge between plates?
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads.
