To charge a capacitor, a power source must be connected to the capacitor to supply it with the voltage it needs to charge up. A resistor is placed in series with the capacitor to limit the amount of current that goes to the capacitor. This is a safety measure so that dangerous levels of current don't go through to the capacitor.

The charge of a capacitor is directly proportional to the area of the plates, permittivity of the dielectric material between the plates and it is inversely proportional to the separation distance between the plates.
C affects the charging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to charge up, which leads to a lesser voltage, V C, as in the same time period for a lesser capacitance. These are all the variables explained, which appear in the capacitor charge equation.
