13.1: Electric Fields and Capacitance

When a capacitor is faced with a decreasing voltage, it acts as a source: supplying current as it releases stored energy (current going out the negative side and in the positive side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance.

Properties of Impedance and Capacitance in a Capacitor

Capacitance and capacitor impedance are two very important concepts in electronics and electrical engineering.. Capacitance is a measure of a capacitor''s ability to store charge. It is measured in Farads (F), defined as the number of Coulombs (C) stored per Volt (V). A capacitor with a high capacitance can store more charge at the same voltage.
