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 purpose of mitosis is to create or produce more cells for a living organism. Mitosis occurs when genetic substance in the nucleus divides or separates in order to create more cells. Cytokinesis normally occurs next and the single cell develops into two separate cells. This same process continues

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

simple values for the purpose of better description and explanation. Say V = 5V‚ R= 1 Ω and L = 1H. Assume inductor is initially uncharged. FIGURE 1 From Figure 1: At t0‚ switch is opened. VL= L (di/dt) . L = 1H di=(Ifinal – Iinitial) = (0 – 5) dt= 0.02s‚ say it takes this amount of time to open the switch. Hence‚ VL = (1) (-5) (0.02) VL = -250 V The electrical potential difference is so great that the air between the contacts of the switch might ionise to provide a

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic
