How do capacitors work?
1909: American inventor William Dubilier (1888–1969) develops compact capacitors using mica as a ceramic dielectric. According to Popular Science (December 1921, p.29), this brilliant invention earns him "over $1,500,000."
19.5 Capacitors and Dielectrics
Note also that the dielectric constant for air is very close to 1, so that air-filled capacitors act much like those with vacuum between their plates except that the air can become conductive if the electric field strength becomes too great. (Recall that E = V / d E = V / d for a parallel plate capacitor.) ...
