Diode a nonlinear device that is used to control the direction of current in a circuit. It is made by combining a piece of p-type and a piece of n-type semiconductor. The layer between p-type and n-type semiconductors is called the depletion region which is made of immobile carriers. A diode has two terminal pins; … Read more
The diode is a unilateral electronic device. It has two terminals termed – Cathode and Anode. When the diode is forward biased i.e., the anode is kept at a higher potential than the cathode, then ideally, the diode acts as a short circuit (zero resistance) and a large current will pass through it even if … Read more
Most of us always use the terms circuit and network interchangeably. Actually it is not so. The two terms have a significant difference between them. In this article, we will remove the confusion and see what is the difference between circuit and network. Let first see the basic definitions. What is Network? A network is … Read more
Proton and neutron are the particles that are found at the center of an atom and both particles comprise the nucleus. Apart from electrons, protons and neutrons form the nucleus of an atom. In this article, we will discuss what is the difference between proton and neutron. Difference between Proton and Neutron in tabular form … Read more
The output of a practical rectifier is not pure DC. The output current or voltage contains both DC as well as AC components. The presence of the AC component in the DC component causes ripples. Ripple factor measures the percentage of AC component present in the rectifier output. What is Ripple factor? It is defined … Read more
A scanner is an input device that can scan different types of documents like photographs or a text page. While the process of scanning goes on the document is converted into a digital format which creates an electronic version of that document. This document can hence be viewed and edited on a computer. There are … Read more
Resistance is generally a force that opposes the motion of a body and slows down the performance of the body. In the field of electrical and electronics, the resistance is the opposition offered by the material to the flow of current through it. The S.I. unit of resistance is ohm (Ω). The effect of temperature … Read more
The diode is a two-terminal electronic component made up of semiconductor materials such as silicon, gallium, etc. It is a unidirectional device i.e. it allows current flow only in one direction. A diode is an uncontrolled device. There are different types of diode. The internal resistance of an ideal diode is considered as zero in … Read more
Like Zener diode, avalanche diode is a semiconductor diode that operates especially in the reverse-biased region. It is a type of PN junction diode having the same symbol as the Zener diode. The avalanche diode is designed in such a way that it can withstand the avalanche breakdown without being damaged by the suddenly and … Read more
Schottky diode is a special type of diode made up of metal and semiconductor materials. The schottky diode is named after the name of the scientist Walter H. Schottky, who had discovered the diode for the first time. This diode is also known as surface barrier diode. It is also known as hot carrier diode. … Read more
