The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).
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.
So, the charge time of a capacitor is primarily determined by the capacitor charge time constant denoted as ? (pronounced tau), which is the product of the resistance (R) in the circuit and the capacitance (C) of the capacitor.
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.
A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%). The two factors which affect the rate at which charge flows are resistance and capacitance.
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.
