According to the Electron Theory of Matter, ever matter is composed of minute particles called molecules. A molecule is in turn made up of atoms. Therefore, the atom is the basic building block of the matter.An atom consists of two main parts viz. nucleus and extra-nucleus. The nucleus is the central part of the atom and has two subatomic particles viz. proton and neutron. Whereas, the extra-nucleus is the space around the nucleus in which the electrons revolve around the nucleus in different orbits.In this article, we are going to enlist all the major differences between electron and proton. Although, ... Read More

The terms electricity and magnetism came into existence thousands of years ago and for a long period of time, both the electricity and magnetism are supposed two different and unrelated phenomena. But, in 1820, a Danish physicist Hans Christian Oersted discovered the relationship between electricity and magnetism by his experiment. Oersted found in his experiment that a current flowing through a wire deflects the needle of a magnetic compass placed near to it. By this observation, he concluded that the flow of electric current (or movement of charge) produces a magnetic field in its nearby region.In 1831, Michael Faraday shown ... Read More

Both diode and SCR are types of semiconductor devices that act as a static switch to control the flow of electric current. Both diode and SCR are unidirectional switches used in a number of electronic circuits. One major application of diode and SCR is that both are used for rectification purpose. However, there are many differences between diode and SCR based on their basic definition, construction, working, applications, etc.In this article, we will explain all the major differences between diode and SCR along with their short description.What is a Diode?A diode is a two-terminal PN junction semiconductor electronic device which ...

In electrical and electronics engineering, a periodic vibration in voltage or current is known as oscillation or electronic oscillation. Oscillation in electronics can also defined as a process of repeating cyclic vibrations of voltage or current about its equilibrium value in time.The number of times the cycle repeats per second is known as the frequency of the oscillation and is measured in cycles per seconds or Hertz (Hz).Some energy at a specific frequency is required to produce the oscillations, this requirement is fulfilled with the help of an electronic circuit called oscillator. An oscillator is an electronic circuit which is ... Read More

The electrical power produced at the generating stations is transmitted to the points of utilization which is achieved with the help of grids (an interconnected network for electricity transmission and distribution from producers to the consumers). Based on the devices used and their functionality, the electric power grids are classified into two categories viz. −Conventional grid (or traditional grid)Smart gridMany issues contribute to the incapability of conventional grid to competently meet the demand for consistent power supply. In order to resolving these problems, the smart grids are developed which is infused with the intelligent sensors and controllers, automated switches and ... Read More

The ability of a body to perform work is known as energy. In our daily life, we use a number of sources of energy for doing work. These sources of energy are broadly classified into two categories viz.Conventional Energy SourcesNon-Conventional Energy SourcesIn this article, we will explain all the significant differences between conventional and non-conventional energy sources by considering various parameters such as basic definition, availability, exhaustibility, cost, uses, etc. But, before discussing the differences, it is advantageous to know that what conventional and non-conventional energy sources are.What are Conventional Energy Sources?The sources of energy that are being used for ...

An electrical machine that is used for the conversion of electrical energy into mechanical energy is known as electric motor. Based on the type of electric supply input, the electric motors are of two types − AC motor and DC motor. An AC motor is the one which takes alternating current supply as input and converts it into mechanical energy while the DC motors takes DC supply as input.Present day advancements in the motor technology allows the use of DC motors in several applications from small toys to larger industrial machinery. DC motors come in two variants viz. Brushed DC ... Read More
