How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
Capacitor physics in ultra-near-field heat transfer
Tight-binding models for the electrons are coupled to the electric-field continuum through a scalar potential.

Capacitor
A capacitor (or condenser) is an electrical device that can store energy in the electric field between a pair of closely-spaced conductors (called ''plates''). When voltage is applied to the capacitor, electric charges of equal magnitude but opposite polarity build up on each plate. They are used in electrical circuits as energy-storage devices.

The capacitor stores the same charge for a smaller voltage, implying that it has a larger capacitance because of the dielectric.

How to Test a Capacitor With an Ohmmeter?
Capacitors are also used to smooth out an electrical signal by blocking sudden changes in current flow. This is possible because when AC (alternating current) voltage is applied to a capacitor, the electric field alternates between positive and negative charges which results in a steady DC (direct current) output from the capacitor.
