What is Rectification? Conversion of alternating current into direct current is called rectification. Semiconductor diodes are extensively used for this purpose. How many types of rectification ? There are three common types of rectification: Half wave rectification Full wave rectification Full Wave Bridge Rectification Voltage multipliers rectification Half Wave Rectification An alternating voltage of Time period T is called input ...

The angle between two vectors is referred as a single point, known as the shortest angle by which we have to move around one of the two given vectors towards the position of co directional with another vector.It is found by using the definition of the dot product of two vectors. How to find Angle b/w two vectors? We can find ...

Entropy measures how much thermal energy or heat per temperature.Campfire,Ice melting, salt or sugar dissolving, popcorn making and boiling water are some entropy examples in your kitchen. The concept of entropy was introduced into the study of thermodynamics by Rudolph Clausius in 1856 to give a quantitative basis for the second law. It provides another variable to describe the state of ...

Newton’s law of gravitation can be stated as:”Everybody in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.” Newton went a step further in his analysis of gravity. In his examination of the orbits of the planets, he ...

Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions of vernier scale.LC of vernier caliper is the difference between one smallest reading of main scale and one smallest reading of vernier scale which is 0.1 mm 0r 0.01 cm. Vernier caliper is an instrument used to measure the length, diameter, ...

There are 7 types of electromagnetic radiation which are given in the list below: Light Infrared radiation Microwaves radiations X-rays Ultraviolet radiations Radiowaves Gamma rays What is Electromagnetic Spectrum? The word spectrum comes from a Latin word meaning “form” or “appearance”. Other familiar words from the same root include “spectacle” and “species.” Newton introduced word to describe the rainbow-like image ...

Faraday’s law of induction was discovered through experiments carried out by Micheal Faraday in England In 1831 and by Joseph Henry in the United States at about the same time. *Even through Faraday published his results first, which gives him priority of discovery, the SI unit of inductance is called the henry (abbreviation H). On the other hand, the SI ...
