Capacitors
The most commonly used and produced capacitor out there is the ceramic capacitor. The name comes from the material from which their dielectric is made. Ceramic capacitors are usually both physically and capacitance-wise small. It''s hard to find a ceramic capacitor much larger than 10µF. A surface-mount ceramic cap is commonly found in a tiny 0402 (0.4mm x 0.2mm), 0603 …

5.12: Force Between the Plates of a Plane Parallel Plate Capacitor
We imagine a capacitor with a charge (+Q) on one plate and (-Q) on the other, and initially the plates are almost, but not quite, touching. There is a force (F) between the plates. Now we gradually pull the plates apart (but the separation remains small enough that it is still small compared with the linear dimensions of the plates and we ...

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.

Capacitive Reactance
When a battery is connected to a capacitor as shown in the above figure, electrons are pumped out of the battery and reaches the right side metal plate and accumulates there since it is attracted by the holes (positive) which is provided by positive terminal of the battery.

Initially, a capacitor with capacitance (C_0) when there is air between its plates is charged by a battery to voltage (V_0). When the capacitor is fully charged, the battery is disconnected.

A capacitor connected to an alternating voltage source has a displacement current to flowing through it. In the case that the voltage source is V 0 cos (ωt), the displacement current can be expressed as: = = At sin(ωt) = −1, the capacitor has a maximum (or peak) current whereby I 0 = ωCV 0. The ratio of peak voltage to peak current is due to capacitive reactance (denoted X C). …
