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 both of the conductors are considered to operate with zero voltage or lower voltage than phase wire voltage.Therefore, this article is created for explaining the differences between neutral and earth wire. But, it may difficult to understand the differences between neutral wire and earth in the beginning, so we have ... 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, capacitors, etc. In a DC circuit only resistors are meaningful, because the inductor and capacitor are the frequency dependent elements and for DC supply the frequency is zero. On the other hand, all the three elements, i.e. resistors, inductors and capacitors are functional in an AC circuit.Based on the combination ... 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 of light. The two most common light sensors are photodiode and light-dependent resistor (LDR).In this post, we will take a look at all the differences between photodiode and LDR along with their description. A major difference between LDR and photodiode is that the LDR (Light Dependent Resistor) shows a bidirectional ... Read More

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 before that have a look on the basic description of multiplexer and demultiplexer which is given in this article.What is Multiplexer?A digital logic circuit which is capable of accepting several inputs and generating a single output is known as multiplexer or MUX. Thus, the multiplexer is a type of data ... Read More

Both multiplexer and decoder are types of combinational digital circuits that are extensively used in the transfer of signals in many communication systems. Basically, the multiplexer and decoder both perform almost identical functions, however they are different from each other in many aspects.The major difference between multiplexer and decoder is in their function that is the primary function of a multiplexer is to transmit data while the primary function of a decoder is to interpret a coded data.In this article, we have enlisted all the significant differences between multiplexer and decoder in the table below.What is Multiplexer?The multiplexer or MUX ...

An air conditioner (AC) is a mechanism which is used to regulate the temperature of a closed space by removing the heat from the space and throwing it to an outside area. The cool air then can circulate in the closed space such as a room or a hall.Air conditioners use a cold liquid refrigerant which absorbs the heat from the hotter space (room) in the evaporator and hence cooling down the room. After absorbing the heat, the refrigerant turns into the gaseous state and is put through a compressor to rise its temperature. This gaseous refrigerant then passes through ... Read More

LCD and LED are popular technologies used to display texts and images. Both LCD and LED are extensively used in display screens in various electronic devices such TVs, computers, laptops, smartphones, etc. There are many differences between LCD and LED displays, where one of the major difference is that LCD uses the liquid crystal and cold cathode fluorescent lamp for the formation of image on the screen, whereas the LED uses a PN junction diode which emits light when the current passes through it that is used as backlight in the display.In this article, we will explain the various differences ...

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 the differences between gas turbine and steam turbine on the basis of definition, components, size, cost, efficiency, etc. We also added a brief description of both gas turbine and steam turbine for your reference.What is a Gas Turbine?A gas turbine, also called combustion turbine, is a type of internal combustion ...

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
