In AC electrical wiring, three types of conductors are used viz. phase wire, neutral wire and earth or ground wire. The phase wire is the live wire of the system which carries electric current from source to load. But, sometimes there is a confusion between neutral and earth wire because ... Read More

A closed path followed by electric current is known as electric circuit. Based on the type of electric supply, the electric circuits can be classified into two major types viz. DC circuit and AC circuit.Every electric circuit consists of a number of circuit elements such as energy sources, resistors, inductors, ... Read More

In electrical and electronics engineering, the automation is day by day increasing which makes the use of various types of sensors. There are a lot of photo-sensors or light sensors which are used for making the electrical and electronic circuit automatically operating. The light sensors are sensitive to the intensity ...

Both Multiplexer and Demultiplexer are types of combinational digital circuits widely used in many large-scale digital systems. The major difference between the multiplexer and demultiplexer is in their ability to accept multiple input signals and single input signal respectively.We will explain some other noticeable differences between multiplexer and demultiplexer, but ...

A mechanical device which converts the kinetic energy of some fluid like steam, water, flue gas, etc. into rotational energy to perform work is called a turbine. Based on the source of rotation, the main types of the turbines are −Steam turbineWater turbineGas turbineWind turbineIn this article, we will discuss ... Read More

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 ... 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. ... Read More
