Michael Faraday Research Papers Samples For Students

Abstract

The use of thermistors started when the scientists discovered that metals have a semiconductor property. The inventor of the first operating thermistor is Samuel Ruben. Thermistors are resistors which could vary their resistance with the change of temperature. The industry of thermistor rapidly increases due to its reliability and low price. Then, its uses became wider as more and more devices are installed by the thermistors. As the technology progresses, the use of thermistors in any devices and instruments also developed (Ametherm, np).

Abstract

The discovery of semiconductor property of a metal began the development of thermistors (Lavenuta, np). Samuel Ruben invented the first practical thermistor (Electrotechnik, np), and since then, the demands of such technology increased because it is considered cheap and reliable. Today, there are many industries, devices and instruments that use thermistors. (Ametherm, np).

History

The semiconductor property of silver sulfide (Ag2S) was the first ever recorded NTC (Negative Temperature Coefficient) thermistor and was observed by Michael Faraday in 1833. However, because of the difficulty to produce thermistors, and its applications were less understood, the manufacturing of thermistors came only during the ...

If someone has made an invention to make life easier or to alleviate one’s living condition then the security of the patent for that invention is needed. According to the World Intellectual Property Organization, a patent is an exclusive right of a person for producing something that offers a new solution to a problem. Furthermore, a patent provides the maker with protection for their invention, and this protection usually lasts for 20 years. One privilege of a person who has a patented invention is that the invention cannot be sold, distributed, used or commercially made without the inventor’s consent. This right is usually enforced ...

Introduction

Wireless electricity conduction is a fascinating subject. Such technology is still in its early stages, but the importance of its development will be significant to humanity worldwide. Statistics indicate that the world population is increasing by the day. Many nations are constantly trying to improve the quality of living of their citizens. These trends only serve to reveal the growing demand for energy globally. Wireless electricity is a modern technological concept of transmission of electrical energy to devices without the use of wires. With this technology, it is be virtually possible to power or charge gadgets, without wiring them to a power ...

Introduction

A black hole is a region in space-time, the gravitational attraction which is so large that it can not leave even objects moving at the speed of light, including photons of light itself. The boundary of this region is called the event horizon, and its characteristic dimension - the gravitational radius. In the simplest case of a spherically symmetric black hole Schwarzschild radius is equal to it.
Theoretically, the possible existence of such regions of space-time should be of some exact solutions of Einstein's equations, the first of which was obtained by Karl Schwarzschild in 1915. The exact inventor of ...

Wireless communication refers to transmission of data or signals via electromagnetic waves. In other words, it is a form of communication that does not involve the use of wires. Instead, radio and microwaves are used to transfer data or signal from one device to another. The first wireless transmission system was developed in early 20th century. This system used Morse code which was a combination of dots and dashes or long and short electric signals assigned to each letter of the English alphabet. The signals were sent and received via wires. This enabled transmission of text based information over a long distance. ...
