Investigating Factors Affecting Resistance of a Wire Aim --- Investigate what factors affect the resistance of wire, however in this experiment I am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same. Method ------ 1) Arrange apparatus as shown in the Diagram: 2) Cut a length of wire over a meter long and sellotape to a meter ruler. 3) Attach one positive crocodile clip to 0cm, and move the negative up/down, stopping
An Investigation into Factors Affecting Resistance of a Wire Plan: The possible variables I could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire. I will use cross sectional area of wire and length of wire because I think it will be hard to draw conclusions from the material of wire. I am not doing temperature because it would be hard to get results from and I think they wouldn't be as accurate.
Factors Affecting the Resistance of a Wire The aim of this experiment is to investigate one factor that affect the resistance of a wire. I will do this by performing an experiment. First I will need to identify the factors that effect resistance. There are a few factors that affect the resistance, it is determined by the properties an object has. This is know as resistivity. The factors I can investigate are : Ÿ Temperature Ÿ Length Ÿ Cross-sectional area/width Ÿ Material
of the Wire Affects the Resistance of the Current Passing Through Wire Aim For this experiment, my aim is to investigate how the length of the wire affects the resistance of the current passing through the wire. Hypothesis and Scientific Knowledge When electric current passes through a conductor, there is always a resistance against it. The resistance varies between different types of materials. Although all metals are conductors, some have a higher resistance than the other. For example
Factors Affecting the Resistance of a Metal Wire 1. Investigate some of the factors that affect the resistance of a metal wire. The current and voltage will be measured and then V = IR will be used to calculate the resistance. The potential divider circuit produced better results in the investigation into how resistance depends on the number of identical resistors connected in series, so this circuit will be used for this investigation, too. Variables and Constants 2. Possible
Factors Affecting Osmosis The aim of this experiment is to investigate the factors affecting osmosis. I have chosen to investigate the effect varying concentration of sucrose solution has on the amount of osmotic activity between the sucrose solution and a plant cell. The plant cell I have chosen to use is a potato tuber from which I plan to cut potato chips of equal length which I will place in test tubes filled with varying concentrations at equal volumes of sucrose solution. After a
The Factors Affecting Osmosis in Potato Tissue Planning In this coursework I am investigating the factors affecting osmosis in potato tissue. [IMAGE] Osmosis is defined as the net movement of water molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell membrane, which lets smaller molecules such as water through but does not allow bigger molecules
Factors Affecting Osmosis in Potato Tissue Introduction: I am going to design and modify an experiment used to show osmosis in potato chips in different concentrations of sucrose solution. I am also going to investigate on how potato chips change in volume and weight when placed in different concentrations of sucrose solution. I will also conduct a preliminary experiment before my final experiment. Aim: To investigate the effect of different concentration of sucrose solution on potato

Investigating the Factors Affecting the Time Peiod of a Pendulum Aim: To investigate the factors affecting the time period of a pendulum Introduction: [IMAGE]The time period of a pendulum is the amount of time that a pendulum takes to swing from position A, through positions B and C and back to A again. It is the movement from 1 peak to another, i.e. one oscillation. I need to examine the factors affecting how long it takes for 1 oscillation to take place, In relation to the energy
threads is a unique type of yarn, engineered and constructed to pass through a sewing machine swiftly. The fundamental function of a sewing thread is to produce aesthetic and performance in stitches and seams (Coats 2003; Shaeffer 2000). 5.1.1 Factors affecting aesthetics of sewing thread Fineness/thickness, colour and lustre must be taken into account when selecting a sewing thread for decorative purposes such as embroidery. Other considerations include: • Hue and shade matching
The Length of a Wire Affects Its Resistance Scientific Enquiry: I know that metals are good conductors of electricity. Metals are good conductors because their electrons are easily released allowing electricity to flow. The electrons can carry current because they split up from the positive ions, so they are free to move and to carry current. Factors that affect resistance: 1. Length – the longer the wire the more atoms there are for the current to push through. 2. Width –

planning, organizing, leading, and controlling. These seem to effect how the internal and external factors affect the four functions of management. Some of these factors are globalization, technology, innovation, diversity, and ethics. External factors affecting the four function of management is different to internal factors. Every company is different and unique in its own way. One of the most important factors is competition, which drives every manager the own way of them thinking. If competition releases
outbreaks are being increasingly reported as a significant constraint to the aquaculture sector, affecting the economic development of the sector in many countries, both developing and developed (Bondad-Reantaso et al., 2005). Bacterial pathogens probably cause more disease problems in aquaculture than all other causes combined (Meyer, 1991). Vibriosis is the well-known cause of severe losses, affecting fish as well as molluscs and crustaceans. Several epizootics of vibriosis have been reported worldwide
by Lilly and Stillwel (1965) to express growth-promoting factors produced by microorganisms. Parker (1974) first specified designation “Probiotic”. He defined probiotics as microorganisms or substances, which contribute to the balance of the intestinal micro flora. Probiotics are biological products, which stimulate the immune system and increase its defensive activity against pathogenic bacteria. Probiotics stimulate the natural resistance of the organism by increasing the number of antibodies and
Bipolar due to Medical Condition is the second diagnosis being considered for the case of Fernando. Bipolar due to Medical Condition is being entertained due to Fernando’s goal-directed activity at work, apparent decreased need for sleep, as well as his excessive involvement in activities that have a high potential for painful consequences such as his diet, use of alcohol, and cigarette use that has lasted much more than a week’s duration. These considerations meet criteria A and B. However, criterion
within this period affecting how the resistance training done previously will impact hypertrophy, naturally one would want to weed out things to limit or to even cut out of a diet. In a scientific study, it was concluded that, “...daily overfeeding with protein and carbohydrates in conjunction with resistance training for eight weeks does not improve body composition and muscle performance or increase the concentration of markers indicative of MPS and myogenic activation in resistance-trained men.”(Spillane
This study will try to transfer the experience of American banks in adoption of mobile banking to Egyptian banks in order to help them to overcome their consumer 's resistance to use mobile banking. I expect that my work in US under the Fulbright award will benefit both me and host institution, our academic institutions, and society in general. The Fulbright award will provide me and host institution the opportunity
the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some research on the factors that affect a circuit's resistance. I am able to predict that the copper wires which will measure 33cm, 66cm and 99cm will have resistances which will increase as the wire gets longer, so therefore the 33cm wire
