Capacitor
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, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.

Electrolytic Capacitors
Electrolytic capacitors are more complicated than electrostatic capacitors in their construction. The function of electrolytes is to provide an electrical connection to the first electrode with a very high surface with fine structure and thus to achieve high capacitance values. The capacitors have an anode and a cathode, and thus they are polarity dependent. Between …

In the previous tutorial, we learned about signal behavior and the role of a capacitor in a circuit. A capacitor stores electrical charge in the form of the electrostatic field in response to an applied voltage. It charges whenever the applied voltage increases (relative to the current-voltage across the capacitor) by allowing a charging current until the voltage across it …

Capacitors in Series and in Parallel: The initial problem can be simplified by finding the capacitance of the series, then using it as part of the parallel calculation. The circuit shown in (a) contains C 1 and C 2 in series. However, these are both in parallel with C 3. If we find the capacitance for the series including C 1 and C 2, we can treat that total as that from a …
