CHAPTER I INTRODUCTION Background of the Study With limited sources of electricity in the Philippines, we discerned that this problem needs attention or better yet solved. At present, Mindanao today has been experiencing power shortage because of lack of hydroelectric energy for the power depends on the availability of Maria Cristina Falls’ water, which is also affected by weather conditions. In view of this, people from the place tend to find an alternative source of energy. We have found

vertical circulation of ocean waters creates currents. Major causes of ocean currents are wind, friction, gravity, and variations in water density in different parts of the oceans. These currents modify local climates. They distribute the heat energy form one latitude to another. Let us learn now about the circulation of ocean currents. The Currents : An ocean current can be defined as a horizontal movement of seawater at the ocean’s surface. Ocean currents are driven by the circulation of wind

and founded company named Edison Illuminating Company. He switched on his first electrical power distribution center in 4th of September in 1882. It provided 110 volts of direct current aka DC for customers in Manhattan. When he was expanding his distribution network his competitors started installing alternating current system and

In 1989, “Back to the Future 2” was released in theaters. From that day on, people had become enamored with the idea of a hover board. A form of transportation that didn’t require the use of wheels. One that did not have the problems of traveling over various types of surfaces. Whether it was grass, dirt, concrete, or water. The hover board would move as long as there was enough momentum and a way for the person to push the board forward. In the 27 years since the movie, many people have tried to

electricity to homes, businesses and industry, all of which were made possible by electrical engineers. Some of the most prominent pioneers in electrical engineering include Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio) and Philo T. Farnsworth (television). These innovators turned ideas and concepts about electricity into practical devices and systems that ushered in the modern age. The field now covers

researchers because these media can support negative reflection and refraction. That is; when a perfect electric conductor (PEC) interface is placed in a chiral nihility medium, only a backward wave can be seen as a reflected wave, whereas in chiral media two reflected forward waves can exist [7,22-25]. is the modal effective refractive index. For guided modes to occur within the core and evanescent tails within the cladding we require: 0 and 0 2 2 2 2 c f k k . For surface modes to

“Cyborg: a person whose body contains mechanical or electrical devices and whose abilities are greater than the abilities of normal humans” (Merriam-Webster). Neil Harbisson, self-proclaimed cyborg is standing on the platform at the TED Global Conference 2012 in Edinburgh, Scotland in quite a colorful ensemble with something that looks like a microphone attached to his head. This immediately captures my attention and I start wondering where this is going to go. Harbisson is both human and machine

Abstract-This paper is based on the “Three phase motors protection” from various faults. This paper emphalis on various difficulties such as phase reversal in single and three phase systems, dropout of line, damage due to overload, failure of single phase there will be usually recommended to perform in complex environmental conditions. This includes in built cut-off frequency having several facilities together with timer in off condition and a starter which is automatic. This main circuit of this

Electricity is a form of energy resulting from the existence of charged particles such as electrons either statically as a charge as a current. Electricity has to do with electrons by When these electrons move between the atoms, a current of electricity is created. But since electricity is a natural force that exists in our world, it didn't have to be invented. Most of the people give credit to Benjamin Franklin for discovering electricity, but Benjamin Franklin had one of the greatest scientific

Nikola Tesla Hi today we will be talking about an australian immigrant named Nikola Tesla he was born on July 10,1856 in smiljan croatia.But today it is now just croatia in his time Tesla went to america to become an inventor in 1884.Back then thousands of immigrants were all crammed on to one boat and if they wanted to bring anything valueable there was a little space for lugage.When Nikola went to america he worked with Thomas Edison over time Tesla and Edison grew to be ferice competers but rather
