3.2: Rectification
3.2.1: Half-wave Rectification. To understand the operation of a single diode in an AC circuit, consider the diagram of Figure (PageIndex{1}). This is a simple series loop consisting of a sine wave source, a diode and a resistor that serves as the load.
An Introduction to Filters
The four primary types of filters include the low-pass filter, the high-pass filter, the band-pass filter, and the notch filter (or the band-reject or band-stop filter). Take note, however, that the terms "low" and "high" do not refer to any absolute values of frequency, but rather, they are relative values with respect to the cutoff frequency.
Capacitor
Introduction. A capacitor is an electronic component which consists of two metallic plates being separated by a region of no conductivity. Either a vacuum or an electrically insulating material could act as a non-conductive region in a capacitor. ... Because the electrode is an independent component in film-foil capacitors, it is the primary ...

Capacitors, Part 1 The Basics of Capacitors
A capacitor, as its name implies, is capable of storing a fairly large electrical charge, provided that its construction allows a large electrode surface area, and a dielectric with suitably high dielectric constant is used.
What Is A Capacitor? How Does A Capacitor Work?
It''s important to note that some capacitors may require specialized testing equipment or procedures, especially in specific applications or high-voltage capacitors. ... Energy Storage: The primary …
Capacitor Bank: Definition, Uses and Benefits
A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system.Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material. Capacitor banks are used …
An introduction to capacitor based Power Factor Correction circuits
Inductive loads such as chokes, motors, inductive heating equipment, generators, transformers, and arc welding equipment produce an electrical lag that is commonly referred to as inductance. ... 0 comments on An introduction to capacitor based Power Factor Correction circuits.
