Wind energy is the kinetic energy generated by virtue of the movement of large air masses caused by differential heating of the atmosphere by the sun. It is one of the clean, renewable energy sources that hold out the promise of meeting a significant portion of energy demand in the direct, grid connected modes as … Read more
Solar energy is a primary source of energy which directly obtained from the sun by capturing the solar radiation and converting it into another form of energy to perform various useful activities. The solar energy received by the earth is approximately 1.4 kW/m2. It is known as Solar Constant or Solar Irradiance. For receiving the solar … Read more
If you compare Ice and Water, the better conductor is obviously water. But why water is the better conductor than Ice? water contains very few ions which are responsible for conduction of electricity. Note: Pure water means water that does not contain ions. This water is water used in batteries. This water is not suitable … Read more

Genetic Algorithm (GA) Genetic Algorithms are the heuristic search and optimization techniques that mimic the process of natural evolution. A genetic algorithm is a local search technique used to find approximate solutions to Optimisation and search problems. It is an efficient, and effective techniques for both optimization and machine learning applications. It is widely-used today … Read more
Meissner’s Effect The repulsion of magnetic flux from the interior of a piece of superconducting material as the material undergoes to the transition to the superconducting phase is known as Meissner’s Effect. In superconductor B = 0 µo( H + M ) = 0 M = − H ……………………. (1) Also, M = χmH ……………. (2) from … Read more
There are two types of superconductor materials Type-1 superconductor Type-2 superconductor Type-1 superconductor They are also called as Soft Superconductor. Their critical field and transition temperature are low. They exhibit complete Meissner’s and Silsbee rule. The change of state from normal to superconductivity and vice-versa is abrupt. Examples: Zn, Pb, Hg, Al, In, etc. Type-2 superconductor They are also called as Hard Superconductor … Read more
Before selecting an insulation system for a particular application, the following properties need to be considered. Mechanical Thermal Environmental including chemical Electric Economic 1. Mechanical properties The mechanical properties considered are the tensile strength, elongation, tensile modulus, compressive modulus, impact strength etc. 2. Thermal properties Include temperature and time of exposure. In this, the important … Read more
In previous, article we discussed ECG (Electrocardiogram). In this article, we will see about different types of ECG. The type of ECG monitoring depends on the frequency and severity of symptoms. There are three types of ECG monitoring i.e. resting ECG, stress ECG, and ambulatory ECG. Ambulatory ECG is divided into 3 groups i.e. Holter monitors, … Read more
In single crystal material such as iron, the magnetic properties of a material depend on the direction in which they are measured. This property of the magnetic material is called as Magnetic Anisotropy. There are three methods to induce Magnetic Anisotropy Cold Working Magnetic Annealing Magnetic Quenching 1. Cold Working such as cold rolling induced the uniaxial magnetic … Read more
