Simple Explanation of Capacitor ESR | DigiKey
Equivalent series resistance (ESR) (represented by R esr in Figure 1) describes losses associated with moving charge through a capacitor. The resistance of the electrode and lead materials is a contributing factor, and losses occurring within the dielectric material itself also occur and are often dominant.
Introduction to Capacitors, Capacitance and Charge
Introduction to Capacitors – Capacitance The capacitance of a parallel plate capacitor is proportional to the area, A in metres 2 of the smallest of the two plates and inversely proportional to the distance or separation, d (i.e. the dielectric thickness) given in metres between these two conductive plates. ...
