Capacitance is proportional to the area of overlap and inversely proportional to the separation between conducting sheets. The closer the sheets are to each other, the greater the capacitance. An example is the capacitance of a capacitor constructed of two parallel plates both of area separated by a distance .
capacitance: farad (F) heat capacity: joule per kelvin (J⋅K −1) constant of integration: varied depending on context speed of light (in vacuum) 299,792,458 meters per second (m/s) speed of sound: meter per second (m/s) specific heat capacity: joule per kilogram per kelvin (J⋅kg −1 ⋅K −1) viscous damping coefficient kilogram per ...
The relationship between capacitance, charge, and potential difference is linear. For example, if the potential difference across a capacitor is halved, the quantity of charge stored by that capacitor will also be halved. For most applications, the farad is an impractically large unit of capacitance.

A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
For example, according to the capacitance row of the table, if a capacitor has a capacitance of 1 F in SI, then it has a capacitance of (10 −9 c 2) cm in ESU; but it is incorrect to replace "1 F" with "(10 −9 c 2) cm" within an equation or formula. (This warning is a special aspect of electromagnetism units.
Body capacitance was a significant nuisance when tuning the earliest radios; touching the tuning knob controlling the tuner's variable capacitor would couple the body capacitance into the tuning circuit, slightly changing its resonant frequency. Design of such circuits intended to be adjusted by a user must prevent interaction of the user's ...
