We can draw many field lines for each charge, but the total number is proportional to the number of charges.) The electric field strength is, thus, directly proportional to (Q). Figure (PageIndex{2}): Electric field lines in this parallel plate capacitor, as always
A capacitor is a device used to store electrical charge and electrical energy. …
For the parallel plate capacitor, electric field was constant between the plates all the time, therefore the energy density, energy per unit volume, is also constant. For the spherical as well as the cylindrical capacitors, the electric field is a function of the radial distance; therefore it will change point to point along the radial distance.

This produces an electric field opposite to the direction of the imposed field, and thus the total electric field is somewhat reduced. Before introduction of the dielectric material, the energy stored in the capacitor was (dfrac{1}{2}QV_1). After introduction of the
In chapter 15 we computed the work done on a charge by the electric field as it moves around a closed loop in the context of the electric generator and Faraday''s law. The work done per unit charge, or the EMF, is an example of the circulation of a field, in this case the electric field, (Gamma_{E}).
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.

Figure 19.13 Electric field lines in this parallel plate capacitor, as always, start on positive charges and end on negative charges. Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the
A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or in an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material). ...
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.

Whenever an electric voltage exists between two separated conductors, an electric field is present within the space between those conductors. In basic electronics, we study the interactions of voltage, current, and resistance as they pertain to circuits, which are conductive paths through which electrons may travel.
The Capacitors Electric Field Capacitors are components designed to take advantage of this phenomenon by placing two conductive plates (usually metal) in close proximity with each other. There are many different styles of capacitor construction, each one suited ...
