2006 "Ohm’s Law is the relationship among electric current‚ resistance‚ and voltage. The principle is named after the German scientist George Simon Ohm." Webster’s Online Dictionary. I will be discussing the uses of Ohm’s Law and why it is so important in everyday electrical problems whether it be simple or not. It is everywhere and used by many whether they notice it or not. Ohms law states that current in amperes is equal to voltage divided by resistance. This form of ohms law is most useful

Joseph Corey‚ Chris‚ Grant Thermodynamics – Enthalpy of Reaction and Hess’s Law I. Purpose The purpose of this lab is to verify Hess’s Law through the three reactions of NaOH and HCl‚ NH4Cl and NaOH‚ and NH3 and HCl. The sum of the enthalpies of the first two reactions should equal the enthalpy of the third reaction. II. Background Hess’s Law is used to determine the enthalpy of a reaction from adding two or more preceding reactions. To determine the enthalpies of certain

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

Abstract: This report will show the acquired understanding of the refrigeration cycle by using first and second laws of thermodynamics. In order to analyze this system several assumptions where made such like an isentropic process at the compressor an isenthalpic expansion in the throttling valve. Diagrams will be provided to depict these thermodynamic processes in addition to computing the heat transferred to the system and the work input to the compressor. Table of Contents Abstract .

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under
