Earth is used as an electrical conductor for electricity by man over 270 years back. The other name for Electrical Earthing is Grounding. Electrical earthing is done to protect ourselves from shock during fault conditions. The common electrode used for Earthing is copper, which is used for grounding. The basic requirement of every household or industry is to maintain proper Earthing. The main purpose of the grounding or earthing systems is to provide a … [Read more...]
Basics of Electricals
Electrical Generator – Working, Types and Applications
How do power stations provide electricity to thousands of houses they don't use huge batteries they do that by spinning a turbine attached to an Electrical Generator. Some power stations use very hot steam that blows over the turbines and spins it or else they use the energy of the falling water. Another example could be using windmills. The basic idea is that if you take a wire and move it up or down inside a magnetic field it induces an electric current. … [Read more...]
Electrical Fuse Types and Their Uses
Early 1860 telegraphs and lighting equipment are protected by means of a wire which is called an Electrical fuse. Thomas Edison first discovered an Electrical fuse as a part of an electric distribution system. An Electrical fuse is a protective device in which a thin material of a low melting point is used. It acts as a protective device when an excessive current beyond its permissible value is flown. The fuse operation depends on inverse-time … [Read more...]
What is Phase in Electricity – Difference Between Single and Three Phase
The electrical energy produced at power stations is transferred through transmission lines. Then, distributed to substations by primary distribution. Finally to domestic consumers through secondary distribution. Homes and small premises are connected with single-phase power. But usually, we find that three-phase power is more preferred over single-phase power. The three-phase machinery is more adequate than a single-phase. Let us discuss in detail … [Read more...]
What is a Deaerator – Working, Types & Applications
Generally, we use certain equipment to generate Electricity. Among them, a boiler plays a key role. For the proper function of the boiler and in order to avoid corrosion inside the boiler we use the deaerator. In the deaerator, the contaminations which are present inside the feed water will be removed. In this article, we will discuss what is a deaerator, working principle, different types of deaerator, its advantages, disadvantages, and … [Read more...]
What is a Polarity Test – Importance, Testing Methods
Generally, whenever a current is flowing in a conductor there is always question whether it is a phase or a neutral. To know this, we check the wire with the help of an electrical tester. In the case of batteries, one acts as a positive terminal and the other acts as a negative terminal which is a DC supply. Here the current has only one direction which does not alternate. Coming to an AC supply, the Current direction will get reversed for every cycle … [Read more...]
What is Biot Savart Law – Expression, Example and Applications
The fundamental relationship between an electric current and a magnetic field is given by biot and savart. Biot and savart is a fundamental of magnetostatics which plays a key role which is similar to coulombs law. Biot and savart conducted several experiments by taking the deflection of compass needle measuring the intensity of the magnetic field of a current, varying in both magnitude and shape and came to a conclusion that a current-carrying element … [Read more...]
What is an Electrostatic Precipitator – Working, Types and Applications
Generally, in power plants, steam generated by the burning of fuels produces certain gases. These gases are released into the atmosphere through a chimney. These gases contain several harmful particles in the air will be absorbed by the living organisms on the earth. Due to these gases, the health of humans and other organisms also will be affected. The environment will be polluted and global warming arises due to these pollutants. So, in order to overcome … [Read more...]
Electrical Components used in Electronics and Electrical Projects
There are numerous important basic electrical components commonly found in the circuits of almost all peripherals. These devices are the essential building blocks of electronic and electrical circuits. These electric components can be found in great numbers on motherboards, video cards, hard disk, logic boards and everywhere else in personal computers. The electrical circuit components can be combined with each other and with dozens of other devices. … [Read more...]
What is a Memristor – Construction, Types, Benefits & Applications
In the year 1971, the theory of memristic was developed by Professor “Leon Chua”. The behavior of the memristor was discovered by an ‘HP Lab Scientist’ while he was trying to find out cross bar switches. Memristor is a switch used to connect several inputs to several outputs in a matrix – that’s why it is also known as matrix switch. Professor Leon Chua had looked at the examples of resistor, capacitor & inductor – from which, he saw a missing … [Read more...]
