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

1. INTRODUCTION & BACKGROUND 1.1. Introduction Change‚ in general‚ indicates any act of making something different. The factors that necessitate change in organizations are broadly categorized into people‚ technology‚ information processing and communication‚ and competition. Some changes in the organization occur suddenly without the conscious efforts of the people. These are called unplanned changes. On the other hand‚ some changes are initiated by the management to accomplish certain goals

Antimicrobial Resistance: Public Health Issue and Role of Nurses in Prevention Antimicrobial resistance is a significant global issue with serious implications for human health. The microorganisms that were previously sensitive to antibiotic treatment are now capable of withstanding attacks by antimicrobial medicines. One of the main reasons that cause antimicrobial resistance is the misuse of antibiotics‚ which includes an inappropriate selection of antibiotic type‚ dose‚ route‚ or duration of

Antibiotic resistance In recent years a challenge to the effective treatment of an ever-increasing range of infections caused by microbes is antimicrobial resistance (AMR). AMR results in reduced effectiveness of antibiotics‚ making the treatment of patients very difficult and sometimes impossible. The impact on especially susceptible patients is most evident‚ resulting in prolonged illness and increased mortality. The total problem caused by AMR on medical field in general and healthcare sector

Civil resistance is political action that relies on the use of nonviolent resistance by civil groups to challenge a particular power‚ force‚ policy or regime. Civil resistance operates through appeals to the adversary‚ pressure and coercion: it can involve systematic attempts to undermine the adversary’s sources of power‚ both domestic and international. Forms of action have included demonstrations‚ vigils and petitions; strikes‚ go-slows‚ boycotts and emigration movements; and sit-ins‚ occupations

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

negatively affects employee morale and productivity.” While people who lose their jobs can be strongly impacted by loss of financial security‚ fear for the future‚ and even decreased self-esteem‚ it’s important to recognize that people who survive job cuts face their own set of negative consequences. This group of “survivors” may experience stress as well as feelings of anxiety or depression. This paper examines these issues by reviewing the numerous organizational and leadership changes that have taken
