While inductors store a current as a magnetic field, capacitors store voltage as an electrostatic field. Capacitors come in many sizes and shapes depending on the manufacturer and their intended use. A capacitor is constructed of two conductive surfaces separated by an insulator to store an electrostatic field between those surfaces.

In other words, capacitors tend to resist changes in voltage drop. When voltage across a capacitor is increased or decreased, the capacitor "resists" the change by drawing …
AC Capacitance and Capacitive Reactance
Capacitors store energy on their conductive plates in the form of an electrical charge. The amount of charge, (Q) stored in a capacitor is linearly proportional to the voltage across the plates. Thus AC capacitance is a measure of the capacity a capacitor has for storing electric charge when connected to a sinusoidal AC supply.

Electrostatic sensors – Their principles and applications
In many applications an array of electrostatic sensors is often used to cover a specific sensing area of the target object or process being monitored. For instance, a number of exposed strip electrodes (Fig. 2 (j)) can be used to sense the charged particles in a square shaped duct, such as those encountered in some circulating fluidized beds and …

The Field Force and the Field Flux. Fields have two measures: a field force and a field flux.The field force is the amount of "push" that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage ("push") and current (flow) through a …
