In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Capacitors
At some point the capacitor plates will be so full of charges that they just can''t accept any more. There are enough negative charges on one plate that they can repel any others that try to join. This is where the capacitance (farads) of a capacitor comes into play
8: Capacitance
The total capacitance of this equivalent single capacitor depends both on the individual capacitors and how they are connected. Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily 8.
Capacitor Theory
Capacitors consist of conducting surfaces separated dielectric (insulator). The effect of this is that when a voltage is applied, charge flows into the capacitor and is stored. When an external circuit is connected to the capacitor, this stored charge will flow from the ...
What Does a Capacitor Do | Explanation | Albert Resources
Capacitance quantifies how much charge a capacitor can store per unit of voltage. The higher the capacitance, the more charge it can store at a given voltage. This is represented in the equation Delta V = frac{Q}{C}, which relates the voltage ( Delta V ) with the charge stored ( Q ) and the capacitance ( C ).
