Zener Diode

What is a Zener Diode? Zener Diode sometimes also known as breakdown diode is a pn junction diode with quite a high doping level especially formulated to operate in reverse biased condition. These are known as special type of semiconductor devices that allows flow of current in both the directions i.e., forward and reverse. Before […]

Power Supply System and its Types

What is Electric Power Supply System? An electric power supply system is a network that provides the generated electricity to the electrical device so that it can be utilized in the form of usable power. To whatever the device, the power supply is connected, it must drive the load of the device. In simplest terminology, […]


What is Electronics? Electronics is known to be the branch of engineering that deals with the study of nature exhibited by electrons under the action of the applied electric field. Electronics is the derivation of electron mechanics. More simply, we can say electronics is the combination of physics, engineering, technology, and applications dealing with the […]

Photovoltaic System and Its Components

The photovoltaic system, which is also referred to as  PV system or solar power system is a system that converts incident solar energy/ sunlight into usable electric power. In our today’s content, we will talk about the photovoltaic system and its components. Introduction Increasing global warming concerns and energy security issues have made solar energy […]

Secondary Emission

What is Secondary Emission? The phenomena of emission of electrons from the surface of solid metallic material by the action of a stream of charged particles are the secondary emission or secondary electron emission. Caesium oxide is an excellent target material that holds the ability to release ten times more current of secondary emission than […]

Thermionic Emission

What is Thermionic Emission? Thermionic emission is a single term that describes an act of liberation of ions when thermal agitation is provided. The combination of the words thermionic and emission to form a single term is used to describe the release of subatomic particles (specifically electrons) by the action of heat. This is so […]

Diffusion Current

What is Diffusion Current? The term ‘diffusion’ signifies a process in which there is a motion of molecules of substance from a region of higher concentration to a lower concentration. Diffusion Current is the current produced as a result of the motion of charged carriers due to the difference in concentration between two regions. In […]

Drift Current

What is Drift Current? In a general sense, the term drift signifies motion or movement towards something. So, the use of the word “drift” with current corresponds to the generation of current due to some specific motion or movement. It is defined as an electric current produced as a result of the motion of charge […]
