The report is of determining some features of the dry cell including the electromotive force and internal resistance of the cell. The current values together with the terminal voltage are recorded after connecting the cell in series with a resistor of a lower value…

This research tells that electric current can be described as the manner in which the electric charge flow in a circuit in order to transfer energy portions to regions of resistance like resistors, buzzers, or bulbs) in the circuit. The circuit gets the energy at the start of the circuit where dry cells are producing electrical energy from chemical energy. The batteries available in today’s markets are mostly constructed from materials that possess negligibly small internal resistance. Real batteries do not only provide voltage to the circuit but they also offer some internal resistance. Any device that produces the voltage purely is called an electromotive force (E.M.F.) Which battery is the total energy that is changed electrical energy during the passage of a unit charge through the production point? It forms a voltage and reflects the total amount of energy supplied through the circuit. The terminal voltage a battery produces at a point without the flow of current is the EMF. The units for measuring EMF is volts. All batteries/cells lose energy as heat when they are dissipating current because of the presence of their internal resistance. The voltmeter is used in the circuit to get the emf values. The addition of a resistor in the circuit drops the reading on the voltmeter voltage, v. Meanwhile, voltage does not experience full transfer in the circuit but a portion of it is wasted due to the presence of internal resistance within the battery. The dry cell only possesses internal resistance which converts the energy present into heat. The dry cells EMF together with its internal resistance can alternatively be calculated by other methods. A plot of terminal voltage versus current can help achieve the above. V varies inversely with changes in I to produce a straight line graph. The line equation of y=mx+c, is applicable to the formula of electromotive force, E= Ir.

This is followed by review of literature and then a conclusion. Thesis statement How can health professionals prevent antibiotic-resistant infection? Introduction Antibiotic resistance may be defined as a type of drug resistance in which the organism survives exposure to the antibiotic that is administered targeting it.
Resistance The gendered and racist nature of violence has been a topic of interest for sociologists since the discourses connecting identity and politics had emerged. One definition for violence has been that it “entails acts of physical coercion or their threat” (Jacobs, Jacobson and Marchbank, 2000, p.2).
Change management is imprtant prcess which helps cmpanies t rebuild their bureaucratic systems and innvate. Thus, resistance t change has different causes and requires different management appraches t level it.
Burke (1992) and Champy (1995) suppse that resistance t change inevitable prcess caused by human needs and expectatins.
The mode of action of antibiotics on microorganism are:- inhibition of cell wall synthesis, damage to the cytoplasm membrane, inhibition of nucleic acid and protein synthesis, inhibition of specific of enzyme systems. (Michael J Pelczar, 5th edition, page 515)
Health care providers, patients and industries all alike contribute to this problem in a number of ways. The health care providers increase drug resistance through the prescription of inappropriate doses for patients. The doses are either to low or
