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.
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.
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
That’s the reason, voltages found across a capacitor do not change immediately (because charge requires a specific time for movement from one point to another point). The rate at which a capacitor charges or discharges, is determined through the time constant of a circuit.
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.
Without V IN, a power source, a capacitor cannot charge. Capacitors can only store voltage which they are supplied through a power source. The larger V IN , the greater the voltage the capacitor charges to, since it is being supplied greater voltage.
