Literature Search Both Design 2 and Design 3 circuits uses the concept of voltage doubler rectifier in particular the Greinacher voltage doubler rectifier‚ where the components used are mainly capacitors‚ diodes. Light emitting diode (LED) and 3-turn coil are also incorporated into Design 2 and Design 3 circuits. There are two main reasons of using a voltage doubler rectifier. Firstly‚ the LED require a forward voltage of 1.7V to 2.2V‚ and the 3-turns coil on the implant will not be able to pick

Why You Should Choose Toroidal Transformers. Transformers are important and highly efficient devices that have incredible applications. Construction mostly distinguishes them and they serve the basic applications. There are different types of transformer applications‚ but toroidal transformer applications are the best. Here are some reasons why you should always use them. Easy to mount. Most toroidal transformer applications do not have very complex designs‚ so you will be able to install them easily

CHAPTER I INTRODUCTION Most mains-operated equipment in use today is connected to the supply via plugs and sockets. These are generally acceptable in benign environments‚ but can be unsafe or have limited life in the presence of moisture. In explosive atmospheres and in undersea applications‚ special connectors must be used. This paper describes a technique‚ the contactless energy transfer system (CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical

TLE Electron The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge. An electron has no known components or substructure. It is generally thought to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth

Hans Christian Oersted was born in Rudkobing on August 14‚ 1777 to Soren Christian Oersted and Karen Hermansen. His father was an apothecary and did not have the time to properly raise Oersted or his brother so they were raised by a German wigmaker. When he turned eleven‚ he went to work for his father at his pharmacy‚ where his first interest in science began. Without any prior schooling‚ except what he learned informally through others‚ he passed the entrance exam to University of Copenhagen‚ where

Extended Experimental Investigation Generating Electricity Physics Teacher: Mr Heagney By: Jesse O’Sullivan Background Information: The history of electrisity leads right back to more than two thousand years ago. Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two. Many electricity-related discoveries had been made by the 17th century‚ including the differentiation between negative and positive currents‚ the classification of matireals as conductors

George Westinghouse was an American entrepreneur and engineer. He was responsible for the introduction and development of altering current for light and power. Westinghouse invented the railway air brake and was a pioneer of the electrical industry. He was one of Thomas Edison’s main rivals in the early implementation of the American electricity system. This man founded 60 companies‚ eventually receiving over 100 patents for his work with the desire to turn ideas into enterprises. George Westinghouse

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he
