CONFIRMING OHM’S LAW BY ALEX KUCHMENKO 9.1 Aim – To Confirm Ohm’s Law through experimentation. Hypothesis – The More Ohms the resistor has‚ the weaker the current will become. Materials – Power pack‚ ammeter‚ voltmeter‚ resistors‚ connecting wires. METHOD – 1. POWER PACK POWER PACK RESISTOR RESISTOR VOLTMETER VOLTMETER AMMETER AMMETER A A V V Set up a known resistor

EM-1 Title: Ohm’s Law‚ Meters‚ Resistivity I Purpose: The basic of simple electrical circuits and measurements is learned. Also‚ investigating the dependence of the resistance of a wire on its length‚ cross-sectional area‚ and the material of which it is made. By examining electrical resistance (R) through a metal conductor‚ the voltage (V) and current (I) through the conductor‚ the following principles will be demonstrated: 1.) Ohm’s Law 2.) Dependence of resistance (R) on the length (L)

Vu Nguyen BIOL 1003/22 ANTIBIOTIC RESISTANCE LAB REPORT Introduction Natural selection is a non-random process in which individual with favorable traits for the environment will likely survive and reproduce than those without these traits. In contrast to Natural selection‚ Artificial selection is the process in which desired traits are intentionally chose to breed among individuals. Antibacterial resistance is the process in which strong and highly resistant bacterial is selected against weaker bacterial

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked

PHY 114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average

Mechanisms of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related

Simon Ohm was born on March 16th‚ 1789. He died on July 6th‚ 1854. He was a German physicist. As a high school teacher‚ Ohm began his research with the recently invented electrochemical cell [ (Unknown.) ] Using his own equipment‚ Ohm determined that there is a connection between the electrical forces (voltage) applied across a conductor and the resultant electric current. This known as Ohm’s law‚ which is named after him. Ohm was born in Erlangen‚ Bavaria. His parents were Johann Wolfgang Ohm and

Resistance Band Exercises (Lower Body) To begin with‚ the following resistance band exercises should be performed approximately 1 - 3 times per week. Ideally they should not be performed on consecutive days‚ to allow muscle recovery. As the strength improves‚ the resistance band exercises can be progressed by gradually increasing the repetitions‚ number of sets or resistance of the exercises provided they do not cause or increase pain.
