| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons move because of the battery voltage. The current flows in the opposing direction of the electrons and the electrons flow towards the positive

A CVA (Cerebrovascular accident) also known as a stroke is caused by the sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. The result can be serious disability or death. Each year alone about 150‚000 people in America die from a stroke or are seriously disabled. Stroke is among the top five causes of death. The effect of the patient depends upon where the damage occurs and the severity of the stroke

12 Concepts that Shape the American Way of Life (The concepts below are a compendium of ideas developed by anthropologists and sociologists over the past 40 years. They demonstrate a central tendency which should not rule out a range of differences within each concept.) 1. Assertiveness: U.S. Americans tend to be candid and outspoken in communication with others‚ and they seldom shy away from disclosing facts about themselves. They prefer "direct" questions and respond with "straight" answers

PROJECT Introduction Title: Investigate one factor that affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)

the wire increases‚ the resistance of the wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much voltage is applied through them‚ these materials are known as ‘Ohmic’ resistors. This is because they are said to obey Ohm’s law‚ which states that if a voltmetre is used to measure the voltage (V) of an unknown resistance (R)‚ and an ammetre is used to measure the current (i) through the same unknown resistance‚ then ‘R’ would be given
