TENS 2146 Electric Devices and Measurements Lab 3 Current and Voltage This report was prepared by: L. Wall Fall 2009 Prof. R. Alba-Flores Team Members: J. White‚ L. Wall Conducted on: September 17‚ 2009 Submitted on : September 24‚ 2009 Abstract: In this lab students experimented with light emitting diodes. The student built a basic circuit with two LED’s and resistors in parallel. The results showed that the voltage is the same in parallel. The items that were in series had the

December 30‚ 1936‚ conditions in Flint michigan working conditions were depressing‚ for the working people at the Flint General Motors (GM) Fisher Body plant. On december 30 they simply locked the doors and sat down‚ in reaction to the strike General Motors made a decision to transfer inspectors to other jobs because they would not leave the union. That day‚ General Motors attempted to transport dies out of Flint by rail to other plants with weaker unions so they could continue to manufacture cars

with shock levels starting from 30 volts to 450 volts. Some switches were named us “slight shock”‚ ”moderate shock” and “Danger- severe shock”. As the experiment progressed ‚ the "learner" would begin to grunt at 75 volts; complain at 120 volts; ask to be released at 150 volts; and let out screams at 285 volts. Eventually‚ the learner was to yell loudly and complain of heart pain. At some point the actor would refuse to answer any more questions. Finally‚ at 330 volts the actor would be totally silent-that

Stanley Milgram’s (1963) study of behavioral obedience sought to understand the nature that drives humans to submit to destructive obedience. In his study‚ Milgram deceived his subject volunteers into believing that the experiment they were submitting themselves to involved learning about the effects of punishment on learning. Under this pretext‚ a subject “teacher” was to administer electric shocks to a confederate “learner” for every wrong answer in a word-pairing exercise. The subject was to administer

with increasing intensity. The real focus of the experiment was the teacher and the learner was an actor who never received any shocks. The teacher sat in front of a shock generator‚ which had thirty switches on it. The switches were labeled 15-450 volts. There were subcategories labeled on the switches and it went from “Slight Shock” to “Dangerous: Severe Shock”. (Milgram

For consumers in different regions‚ the company adopted the multi-brands strategy; it means consumers in different region markets like the different brands. For example: Chevrolet is one the most important popular brands in North America‚ on the other hand‚ Cadillac has a certain status in the luxury car market; but in China‚ Buick is the most important popular brands‚ Chevrolet becomes the representatives

electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0.06 volt per pH unit) that is measured and displayed as pH units by the meter. For more information about pH probes‚ see glass electrode. Building a pH meter Because the circuitry of a basic pH meter is quite simple‚ it is possible to build a serviceable

to the positive side of the LED. Another way of finding the positive side is to find a flat spot on the edge of the LED. This flat spot is on the negative side. When current is flowing through an LED the voltage on the positive leg is about 1.4 volts higher than the voltage on the negative side. Remember that there is no resistance to limit the current so a resistor must be used in series with the LED to avoid destroying it. Resistors Resistors are components that have a predetermined resistance
