The basic function of a capacitor is to store energy in an electric field. Capacitors store energy and release it when necessary, in contrast to resistors, which limit the flow of current. A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. ... the stored energy remains in the ...
The RC Delay Element
A capacitor with a higher Farad value can store more energy than one with a smaller value. Therefore it also takes more time to charge a high-value capacitor versus a small-value capacitor. The "speed of the charging" is determined by how much current that flows through the capacitor. The more current that flows, the faster it charges.

6.1.2: Capacitance and Capacitors
Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

How to Solve Parallel Circuits: 10 Steps (with Pictures)
Solving parallel circuits is an easy process once you know the basic formulas and principles. When two or more resistors are connected side by side the current can "choose" it''s path (in much the same way as cars tend to change lanes and drive alongside one another when a one-lane road splits into two parallel lanes).
Series and Parallel Circuits
Notice that in some nodes (like between R 1 and R 2) the current is the same going in as at is coming out.At other nodes (specifically the three-way junction between R 2, R 3, and R 4) the main (blue) current splits into two different ones. That''s the key difference between series and parallel!. …
Capacitors in Series and in Parallel
In fact, since capacitors simply add in parallel, in many circuits, capacitors are placed in parallel to increase the capacitance. For example, if a circuit designer wants 0.44µF in a certain part of the circuit, he may not have a 0.44µF capacitor or one may not exist. So what he can do and what is done many times in professional circuits is ...
