JOULE’S LAW Introduction and research question In this experiment‚ we were going to investigate the resistance R of an immersion heater. We had to make our own heater‚ and measure the resistance using a multimeter. Then we had to measure the current I‚ using an ammeter and a voltmeter. And at last‚ we had to determine the power P of the immersion heater. This experiment would require to make a table with the data collection‚ a graph‚ and a few calculations using Joule’s and Ohms law. Our research

Suzana Milic Thomas Edison V. Nikola Tesla 26 March 2013 Nikola Tesla was born on 10 July 1856‚ in Smiljan‚ now Croatia. He was the son of an Orthodox priest. In history‚ he will be remembered as a scientist who is openly opposed to the then unquestioned scientific authority to Thomas Edison. Tesla insisted on converting DC into AC‚ which even the great scientist Edison‚ did not have in his head. At the very beginning‚ Edison was Tesla’s idol and worked with him for a time as an assistant. He

Introduction: Lighting is an essential service in all the industries. The power consumption by the indusrtial lighting varies between 2% to 10% of the total power depending on the type of industry. Innovation and continuous improvement in the field of lighting‚ has given rise to tremendous energy saving opportunities in this area. The simplest and the most widely used form of controlling a lighting installation is "On-Off" switch. In the electrical lighting system in our community‚ especially

Did Nikola Tesla invent free energy before many years ? Serbian born engineer Nikola Tesla was a technological genius and radical inventor. His work on an alternating current power system‚ the fluorescent light bulb‚ remote control‚ and many other mass market inventions‚ revolutionized the twentieth century. But Tesla’s biggest project – his dream of providing energy to the world for free collapsed when his financial backers unexpectedly withdrew their support. Some believe that Tesla’s free energy

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

involved the capsulation of the sun’s rays through panels of photovoltaic (PV) cells. The encapsulated energy charged a wet cell battery‚ controlled by battery control unit (BCU). It produce direct current (DC) power to run a DC appliances. Additionally‚ DC current can be converted alternating current (AC) to run AC appliances. These applications tested by the PGSEP. The PGSEP was confident that this application able to solve the Philippine’s rural electrification needs most especially in the

POWE INVERTER FOR HOME USE AND SIMPLIFIED CIRCUIT DIAGRAMME POWER INVERTERS Power inverters are simply DC (direct current) to AC (alternating current) converters - they convert DC energy stored in a battery‚ to the electric current (AC) that your appliances require. An inverter taps current from the public supply when that is on (or‚ alternatively‚ from a power generator)‚ stores that power in its battery bank as DC and converts it to AC when the power supply is gone. That way‚ the inverter

Purpose: The purpose of these experiments[1] was to measure the exciting current and determine the core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing
