Capacitor Capacitor is an electrical passive device for storing charge in the form of electric field. In its simplest from‚ It consists basically consists of two conductors which are separated by a dielectric medium (non-conductor) such as air‚ waxed paper‚ plastics‚ etc. The capacitance of capacitor is directly proportional to the surface areas and the inverse of the separation of the two conductors. The dielectric constant of the non-conductor is also affecting the capacitance. FIGURE 1 Capacitor

Meal Worm Cellular Respiration Experiment Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get

color precipitate begins to form. Also‚ the smell of cherries emits from the solution. The solution sat for about 15 minutes before proceeding. A vacuum filtration is then used to obtain a crude product. While emptying the product onto the filter paper‚ not all of the precipitate was removed‚ this may cause a lower percent yield. After a few minutes‚ the vacuum was disconnected‚ and the crude product was rinsed with a little bit of ethanol‚ reconnected and vacuum

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

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

Six months after the attack on Pearl Harbor‚ the United States defeated Japan in one of the most decisive naval battles of World War II. Thanks in part to major advances in code breaking‚ the United States was able to preempt and counter Japan’s planned ambush of its few remaining aircraft carriers‚ inflicting permanent damage on the Japanese Navy. An important turning point in the Pacific campaign‚ the victory allowed the United States and its allies to move into an offensive position. This fleet

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

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”
