History of radio – Definition In St. Louis‚ Missouri‚ Nikola Tesla made the first public demonstration of radio communication in 1893. Addressing the Franklin Institute in Philadelphia and the National Electric Light Association‚ he described and demonstrated in detail the principles of radio communication. The apparatus

flowing through the coil is i = 1 A. (a) Determine the flux in the core. (b) Determine the flux densities in the parts of the core. (c) Find the current i in the coil to produce a flux (φ=0.012Wb). 2. A circular ring of magnetic material has a mean length of 1.0 m and a cross-sectional area of 0.001 m2. A saw cut of 5 mm width is made in the ring. Calculate the magnetizing current required to produce a flux of 1.0 mWb in the air-gap if the ring is wound uniformly with a coil of 200 turns. Take

Corporation. As interest in an alternating-current system grew‚ Tesla and Westinghouse were put in direct competition with Thomas Edison‚ who was intent on selling his direct-current system to the nation. A negative-press campaign was soon waged by Edison‚ in an attempt to undermine interest in AC power. Tesla‚ for his part‚ continued in his work and would patent several more inventions during this period‚ including the “Tesla coil‚” which laid the foundation for wireless technologies and is still

Nikola Tesla championed the alternating current of electric flow‚ which is the means by which electric current is carried in the modern world. Tesla also improved upon the transformer and the electric bulb‚ and invented the Tesla coil. 8. Max Planck is known as the father of quantum mechanics‚ and showed how the energy of a photon is proportional to its frequency

Wireless Charger for Low Power Devices Chapter 1 1.1 Introduction We live in a world of technological advancement. New technologies emerge each and every day to make our life simpler. Despite all these‚ we still rely on the classical and conventional wire system to charge our everyday use low power devices such as mobile phones‚ digital camera etc. and even mid power devices such as laptops. The conventional wire system creates a mess when

Design of Induction Motors Introduction: Induction motors are the ac motors which are employed as the prime movers in most of the industries. Such motors are widely used in industrial applications from small workshops to large industries. These motors are employed in applications such as centrifugal pumps‚ conveyers‚ compressors crushers‚ and drilling machines etc. Constructional Details: Similar to DC machines an induction motor consists of a stationary member called stator and a rotating
