*Fr.: condensateur*
A device for storing electric charge. The simplest sort of capacitors consists of two parallel,
conductive plates having equal amounts of opposite charges and separated by a
→ *dielectric* material.
When a capacitor is fully charged there is a → *potential difference*
between its plates. The larger the area of the plates and/or
the smaller the separation between them the greater will be the charge that
the capacitor can hold and the greater will be its → *capacitance*.
The actual charge *Q* on the plates of a capacitor is given by:
*Q = C . V*, where *C* is the capacitance and *V* the
→ *voltage*. From *capacit-*, from → *capacity* +
→ *-or*. From *gonjân* transitive stem of *gonjidan* "to be contained; to hold exactly; to
be filled," → *capacity*, + *-gar*, → *-or*. |
