Therefore, the net field created by the capacitor will be partially decreased, as will the potential difference across it, by the dielectric. On the other hand, the dielectric prevents the plates of the capacitor from coming into direct contact (which would render the capacitor useless). If it has a high permittivity, it also increases the capacitance for any given voltage.

This is what we wanted to show. The presence of the insulating material makes for a weaker electric field (for the same charge on the capacitor), meaning a smaller potential difference, meaning a bigger charge-to-voltage ratio, meaning a bigger capacitance. How much bigger depends on how much the insulator is polarized which depends on what

6 FAQs about [Capacitor Field]
What is a capacitor in Electrical Engineering?
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.
What is the space between a capacitor called?
(Note that such electrical conductors are sometimes referred to as “electrodes,” but more correctly, they are “capacitor plates.”) The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a “vacuum capacitor.” However, the space is usually filled with an insulating material known as a dielectric.
What is a capacitor & how does it work?
This page titled is shared under a license and was authored, remixed, and/or curated by via that was edited to the style and standards of the LibreTexts platform. A capacitor is a device used to store charge, which depends on two major factors—the voltage applied and the capacitor’s physical characteristics.

Is field strength proportional to charge on a capacitor?
Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor. The field is proportional to the charge: where the symbol ∝ means “proportional to.”
