The English scientist Henry Cavendish (1731–1810) determined the factors affecting capacitance. The capacitance (C) of a parallel plate capacitor is…directly proportional to the area (A) of one plate; inversely proportional to the separation (d) between the plates; directly proportional to the dielectric constant (κ, the Greek letter kappa) of the material between …
Learn MoreSpecial purpose capacitors. These include silver – mica caps, X and Y rated caps, etc. X and Y rated capacitors, for example, are built for line filtering – more robust construction and higher voltage ratings, also low capacitances, to reduce the current passing through it if AC voltage is applied and to limit the energy stored in the cap ...
