Before we go over the details, such as of the formula to calculate the voltage across a capacitor and the charging graph, we will first go overthe basics of capacitor charging. How much a capacitor can charge to depends on a number of factors. First, the amount of charge that a capacitor can charge up to at a certain given.

The Capacitor Charge Equation is the equation (or formula) which calculates the voltage which a capacitor charges to after a certain time period has elapsed. Below is the Capacitor Charge Equation: Below is a typical circuit for charging a capacitor.
This charging current is maximum at the instant of switching and decreases gradually with the increase in the voltage across the capacitor. Once the capacitor is charged to a voltage equal to the source voltage V, the charging current will become zero.
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.
