    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.

    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

    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

    Investigating Resistance of a Wire INTRODUCTION This investigation is about find the resistance of a wire. Resistance is the slow-down of the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. Resistance is measured in a unit called an ohm (Ω). In 1826, Georg Ohm discovered

    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

    mass difference, when placed in different concentrations of sugar solutions. This investigation would expect to have 3 different variables, Independent, which you can change, the thing that I will be changing in this investigation for the factors affecting osmosis, is the concentrations of the solution that changes the mass and investigate osmosis with potato tissues. The different sugar concentrations will be changed to see the result of the potatoes when placed in sugar solutions placed in

    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
