               Sine wave inverter                 Introduction: A sine wave inverter is a type of power inverter that generates an AC waveform with a pure sine wave output. This type of inverter is commonly used in applications where high-quality power is required, such as in sensitive electronics or medical equipment. Working Principle: The basic principle behind a sine wave inverter is to convert DC power from a battery or other source into AC power with a pure sine wave output. This is achieved through a series of electronic components and circuits that work together to create the desired waveform. The first component in a sine wave inverter is a DC to DC converter, which converts the DC power from the battery into a higher voltage DC power that can be used to generate the AC waveform. This higher voltage DC power is then fed into a series of switches that turn on and off at specific intervals to create the AC waveform. The switches in a sine wave inverter are typically controlled b

 This is video in showing the Surya Kiran formation, this formation in pilots use hawk aircraft to show the air formation . In this show total 10 to 12 hawk are used and the work as a team in air with aircraft the pilot has full control to aircraft. The hawk in training aircraft, it's mean they used to train the pilot in academy. And also use in air show to say " don't fear to enemy because we are here to protect you " . ✂  ✂. ✂. ✂. ✂. ✂. ✂. ✂. ✂. ✂. ✂. ✂. ✂.  You know about aircraft or creative knowledge  then follow me 

  what is python? the python created by "Guido Van Rossum (dutch programmer)in 1991.                       ♦   It is used for:  web development (server-side), software development, mathematics, system scripting it is object oriented programming language open source programming  language interpreted language high level language for what to do instead of how to do Easy to learn portable why python?  work on different platform [Linux, window ] syntax similar to English code in fever line execution speed can be Treated in a procedural way libraries what python used for? Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis . Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn't specialized for any specific problems.   Good to know The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, a

  OPERATION SAFED SAGAR Operation Safed Sagar was the code name assigned to the Indian Air Force's strike to support  the Ground troops during Operation Vijay that was aimed to flush out Regular and Irregular troops of the  Pakistani Army from Indian Positions in the Kargil sector along the Line of Control. It was the first large scale  use of air power in the Jammu and Kashmir region since the Indo-Pakistan War of 1971. Ground Operations Initial infiltrations were noticed in Kargil in early May, 1999.  Because of the extreme winter weather in Kashmir it was common  practice for the Indian and Pakistani Army to abandon forward posts  and reoccupy them in the spring. That particular spring, the Pakistan  Army reoccupied the forward posts before the scheduled time not only  theirs but also the posts which belonged to India, in a bid to capture  Kashmir. By the second week of May, an ambush on an Indian army patrol acting on a tip- off by a local  shepherd in the Batalik sector led to

  An  operational amplifier  (often  op amp  or  opamp ) is a  DC-coupled  high- gain  electronic voltage  amplifier  with a  differential input  and, usually, a  single-ended  output. [1]  In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically 100,000 times larger than the potential difference between its input terminals. Operational amplifiers had their origins in  analog computers , where they were used to perform mathematical operations in linear, non-linear, and frequency-dependent circuits. Electronic symbol The popularity of the op amp as a building block in analog circuits is due to its versatility. By using negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc. are determined by external components and have little dependence on temperature coefficients or engineering tolerance in the op amp itself. Op amps are used widely in electronic devices today, including a vas

 FARADES LOW Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated. The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc. Faraday's law is a fundamental relationship which comes from  Maxwell's equations . It serves as a succinct summary of the ways a  voltage  (or emf) may be generated by a changing magnetic environment. The induced emf in a coil is equal to the negative of the rate of change of  magnetic flux   times the number of turns in the coil. It involves the interaction of charge with magnetic field. 

Basic Definitions Mass It is quantity of matter contained in a body. It does not depend upon gravitational force. The  fundamental unit of mass is the Kilogram (kg). Weight Weight is the force exerted by gravity. Weight of body is dependent upon gravitational force, so it is  not constant. Weight = Mass x Gravitational acceleration W =m g Force It is push or pull acting on a body which changes or tends to change the state of rest or uniform motion of the body. As per Newton's second law of motion Force ∝ acceleration F= m a  In SI unit (International system), unit of mass is kg and unit of acceleration is m/s2 and unit of the force is Newton (N). When m = 1 kg, and a = 1 m/s then F = 1 N. 1 N: When unit mass is given unit acceleration then the force produced is 1 N. Pressure It is the force exerted by fluid (liquid or gas) on unit area. It is a property of fluid.  Pressure=Force/Area=N/m² The unit of pressure is known as Pascal (Pa) or N/m2 1 Pa = 1 N/m2 Other commonly used units
