PRINCIPLES OF OPERATION
4.1 BASIC CONCEPTS
4.1.1 Capacitance
The electrical property of capacitance describes the ability of a
component to store charge when subject to an electric potential
(voltage). All matter exhibits this property to a greater or lesser
extent. Personnel on an assembly line, for example, may store a
charge when they introduce friction while walking across a
carpet. That charge poses a potential danger to some integrated
circuits if it should be discharged through the components of the
IC, and care must be taken to “ ground ” personnel working with
charge-sensitive components. Capacitors are electronic com 
ponents specifically designed to store charge.
