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 blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

Resistance in a Conductor: The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. Electrical resistance shares some conceptual parallels with the mechanical notion of friction. The SI unit of electrical resistance is the ohm (Ω).An object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance‚ except

Antibiotic Resistance Nicholas J. Ciotti Nova Southeastern University Biology 1510 Professor A. Hirons March 28‚ 2011 Abstract Antibiotic resistance is when microorganisms‚ such as bacteria‚ are able to survive an exposure to antibiotics and these bacteria are now resistant to the effects of these antibiotics. Antibiotic resistance in bacteria has been an issue since antibiotics were discovered. The fact that bacteria can become resistant to our medical treatments such as antibiotics

Introduction The resistance of a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is

This paper explains the process of Project Management and the risks‚ specifically associated with IT projects‚ that threaten the effective execution and success and implementation of an IT project. It describes in detail the process and tools used in Project Risk Management as well as how to mitigate risks throughout the life of a project. Introduction Changes in technology‚ competition‚ and demand have prompted companies and organizations

Abstract The spread of antibiotic resistance is a universal threat to both humans and animals for treatment of microbial infections. The antibiotic resistance is generally not preventable but can still be controlled. Prolonged and repeated use of antibiotic leads to many pathogen becoming resistant to antibiotics. The resistance may be either intrinsic or acquired depending on the condition. Although classically attributed to chromosomal mutations‚ resistance is most commonly associated with extra-chromosomal

The bridge supply voltage is 100V. Now one of the resistances is changed to 1010Ω. The output voltage is measured by a voltmeter of infinite resistance. Calculate the bridge sensitivity.

Resistance noun/ re-zis-tense Resistance is the process of creating a fair world by voicing the nontrivial injustices that plague society’s institutions and by fighting with action to resolve those inequities. Resistance takes many forms‚ and all of the texts demonstrate the full definition of resistance‚ but the different clauses and phrases will be best exemplified by certain texts. In Persepolis‚ Satrapi shows that the manifestations of resistance that she saw in her childhood ultimately existed

Such effective hiring practices are critical to reducing employee turnover and creating a well-functioning and collaborative organization. Of course‚ interviews constitute perhaps the most foundational means through which candidates can be vetted to ensure effective hiring takes place. The present research examines positive and negative elements

What is Passive Resistance? Passive Resistance is the nonviolent act of resisting to methods of the government‚ a dweller of power‚ or certain laws. Since 1897‚ Mohandas Karamchand Gandhi has acted on this idea‚ after questioning his people’s [Indians] status with the British Empire. There were many protest‚ five in which Gandhi was arrested. When he went to prison‚ he went on hunger strikes‚ greatly embarrassing the British Empire. Gandhi later died in 1948‚ inside of a prison‚ fighting for the
