1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

The Importance of Camouflage By Biology 101 May‚ 29 2013 Introduction In life‚ we have heard the phrase “only the strongest will survive”‚ and undoubtedly‚ think of the strength of a lion or the ferociousness of a bear‚ but this is not always the case to being a dominant species in a community. In this lab‚ we will explore the theory of natural selection‚ or as Charles Darwin put it‚ “Survival of the fittest” (King et al‚ 1-14). Through this concept‚ we will come to the understanding

This semester in English 101 has been very demanding for me. In previous years‚ I generally completed my writing assignments with ease and without having to put much thought or effort into them‚ but this year‚ I was required to work for many hours on each of my papers and to proofread them many times in order to receive a good grade. For example‚ I learned that if I wanted to reach my audience‚ I had to organize my paper in such a way that everyone could easily understand the organization and the

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

Water lab Research Question: How many drops of water can fit on a coin? (Water properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.) Variables: Variables | Type of Variable | How it was manipulated | Independent | Water drops‚ different types of water | Determining how many drops of the

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

Write Up The novel Your Inner Fish‚ by Neil Shubin‚ shows profound knowledge of evolution in the origins of the humans. Shubin writes enthusiastic chapters that specify major organs of general life on earth‚ ranging from aquatic life like sharks to terrestrial animals such as mice. Shubin skillfully explains complex connections to us humans to other present animals with evidence‚ in fossils‚ that show evolution throughout millions‚ even billions of years. How did we inherit all those essential

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Name: Nikia Martinez Class: Biology 240L L3-1201 Assignment: Electrocardiography Lab Report Due: April 3rd 2012 Professor: Dr. B. Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
