Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. Initially
Silver mica capacitor
Ceramic capacitors were also used in the 1920s due to a shortage of mica, but by the 1950s silver mica had become the capacitor of choice for small-value RF applications. [1] This remained the case until the latter part of the 20th century when advances in ceramic capacitors led to the replacement of mica with ceramic in most applications.
