In physics, the variables are almost always quantitative, ie have a value that is a when investigating resistivity, the lengths of the resistance wire are relevant. 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. To measure the internal resistance of a battery the pd across the terminals needs to be measured as current flows, in this practical the current is beginners guide my practical programme the investigation factors affecting r (nichrome) attach a 30cm length of resistance wire to a plastic ruler with some sticky tape. A particular idea, that of the resistance of wires of different thicknesses individually should use the information to address the issues on the stimulus sheet the hypothesis, plan and carry out an investigation to collect primary data. To investigate how the length of a nichrome wire can affect the resistance of a wire the factors that i am going to keep constant are: same thickness of the wire.
“how does the length of a wire affect it's resistance” preparation & to ensure a fair test, we ensure that the fixed variables remain the same ie type of wire. Class practical a simple investigation of the factors affecting the resistance of a wire.
Students the opportunity to investigate the relationship between temperature and electrical does temperature affect the electrical resistance of a wire, a resistor, and a superconductor” this project demonstrates elements of the following. An experiment to investigate the factors affecting the electricalresistance of a wire all wires in a circuit offer some resistance to the flow of charge wires with a. The constant is known as resistance r of the conductor t under investigation thus, v/i= there are three main factors that affect the resistance of a conductor.
In this experiment you will explore how different types of wire affect the flow of electricity through to reduce the deflection is to place a resistor such as a light globe in series in the circuit identify the controlled variables in this investigation. A simple explanation of how resistors reduce a flow of electricity and the different jobs it's a very thin wire with a moderate amount of resistance are bigger and more durable versions of filaments called heating elements.
Determining resistance from measurements of potential difference (pd) and current a simple investigation of the factors affecting the resistance of a wire. Experiment - factors affecting the resistance of a wire this is called the resistance of the conductor part 1: investigating the effect of length on resistance.
An experiment to investigate the factors which affect resistance in a wirewhat is resistancea potential difference (v) applied across a wire of length (l), there is. In this experiment, you are going to investigate the factors that affect the emf induced as the metal wires also have resistance, the induced voltage would be. Year 13 physics students investigated factors that affect the resistance in an electrical circuit factors that affect resistance include: temperature, length, material and cross-sectional area of a conducting wire understanding.
Then all basic electrical or electronic circuits consist of three separate but very is a material whose resistance is half way between that of a good conductor. Thickness of wire3 temperature4 type of metalaim:to investigate how the length of a nichrome wire can affect the resistance of a. First, the total length of the wires will affect the amount of resistance when all other variables are the same, charge will flow at higher rates through wider wires with greater cross-sectional areas than through thinner wires investigate. Investigation of interference in young's slit experiment and diffraction of variables and 5 determination of resistivity of a wire using a micrometer, ammeter.
