Where: In order to charge a capacitor with the simplest method, we will use a capacitor (C), a resistor (R), and a DC voltage source. We connect these components all in series with the addition of a switch. At the initial time, or time zero, the switch is closed and the capacitor is starting to charge up.
Charging of capacitors means we store energy in the capacitor in electric field form between the capacitor plates. How long does it take to charge a capacitor? About 10 time-constant. One time-constant equal to the product of the resistance and capacitance in the RC circuits. The capacitor will be charged about 99.995% of the voltage source.
Connecting the resistor, capacitor, and voltage source in series will be able to charge the capacitor (C) through the resistor (R). Before moving on to the RC charging circuit and capacitor charging formula, it is wise for us to understand this term, called Time Constant.
The Capacitor Charging Graph is the a graph that shows how many time constants a voltage must be applied to a capacitor before the capacitor reaches a given percentage of the applied voltage. A capacitor charging graph really shows to what voltage a capacitor will charge to after a given amount of time has elapsed.
From the above discussion, we can conclude that during charging of a capacitor, the charge and voltage across the capacitor increases exponentially, while the charging current decreases. A charged capacitor stores electrical energy in the form of electrostatic charge in the dielectric medium between the plates of the capacitor.

Charging and Discharging a Capacitor
Charging a capacitor isn''t much more difficult than discharging and the same principles still apply. The circuit consists of two batteries, a light bulb, and a capacitor. Essentially, the electron current from the batteries will continue to run until the circuit reaches equilibrium (the capacitor is "full").
