The Human Battery Do males or females produce the most electric current? Abstract The Human Battery Do males or females produce the most electric current? Abstract The purpose of this project was to determine whether males or females produce the most electric current. An aluminum plate, a copper plate, a micro ammeter, two lead wires with alligator clips, water, notebook paper, and pencil were used as materials. It was predicted that males would produce a greater electric…
Stray current corrosion: Stray current is the current which occurs when conductors are placed between high magnetic or electric fields. Presence of stray currents over the PCB surface can generate corrosion problems. The below figure 5 shows severe corrosion damage to micro wave module for 24 GHz. This equipment is built in controlled conditions where water condensation is possible. After few hours of use, severe corrosion was seen on the surface. Figure 5. Stray current corrosion of a micro…
Chapter 3 Interleaved Buck Converter System 3.1 INTRODUCTION Interleaved Buck Converter has lots of concentration due to its simple and low control complexity in application. where no isolation and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D…
Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…
Right now, I want you to take a look at your phone. When you do this you will find many different components that make your phone, well, your phone. The screen is lit up. Voice transmitting, really making it a phone. There is a camera, which is along the lines of motion photography. Music recorded on your phone, dating back to the first phonograph. And last but not least, a nickel alkaline battery, powering the whole phone. What does this have to do with what I am researching, you may ask? All…
not to compare the two. They worked for years creating and perfecting their various inventions. Edison is best known for creating a commercially viable light bulb, and Tesla is remembered for his contributions to the design of alternating current electricity. Though Edison is more well known, both men contributed greatly to the field of electrical science and should forever be remembered. Thomas Edison was born on February 11th, 1847. He grew up in Milan, Ohio, and later moved to Michigan. As…
perks such as traveling and the knowledge to solve almost any problem. Electrical engineering dates back to William Gilbert, the father of electrical engineering, in the 19th century. Gilbert invented the versorium, a device that detects static electricity. Although a versorium will not be found in every…
In addition to the wide catalog of innovative technology on display, the Exhibition was very well known for hosting some of the most iconic inventors in history. “One new invention which interested hardly anybody, yet which would affect the nation profoundly, was Alexander Graham Bell’s telephone. It attracted less notice than the packages of magic tricks on sale nearby” (Brown 132-133). Although Bell was not a United States citizen at the time, his invention was displayed on American soil and…
Nikola Tesla The inventor Nikola Tesla lived from July 10, 1856 to January 7, 1943, he was a well-known engineer who designed the alternating-current (AC) electric system. He was born in what is now Croatia; he came to the United States in 1884 and worked for Thomas Edison for a while before they both went their separate ways. Tesla sold several patent rights to George Westinghouse; one of those was his AC machinery. During Tesla’s career he discovered, designed and developed ideas for a number…
Abstract – Photocopiers make use of Toner (powder) to form the latent electrical image on the electrostatically charged drum. The paper has to slide over the drum during Xerography process and hence it picks up the toner. Vague issues cause the non-picking of toner particles (approximately 10%) and they are left over the drum. This non-picked toner is termed as Waste Toner (WT). As it adversely affects the quality of proceeding copies, this has to be removed from the drum. A cleaning blade made…
