Niño roel a dela cruz bsme 3a experiment no1 conclusion aside from using devices such as multitester, the resistance value of a resistor can be good equipments should be used such as the resistors, connecting wires, voltage supply and multitester it is slightly more difficult to use an analog multitester than. University physics, lab 4: resistivity measurement in this laboratory experiment, you will measure the resistivity (ρ) of a copper and nickel wire equipment: five- cenco coils mounted on a base (see the wire diameter printed in the base), ammeter, voltmeter, leads, power supply, rheostat (30 ω), single throw switch (s. This experiment was conducted to find out how temperature affects the conductivity and resistance of a wire the experiment was conclusion the hypothesis that when the temperature of a wire increases, the resistance value of the wire will also increase and the conductivity of the wire will reduce is proven to be true. How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire current is the rate. An investigation into the resistance of a wire free gcse physics coursework essay. This activity is taken from advancing physics chapter 4 340e tap 112- 2: introduction to resistivity using conducting paper how the dimensions of a conductor affect its resistance in this experiment you will use conducting paper to find out how the size and shape of a material affect its resistance, even though the material.

I determine the resistivity of constantan and compare it to a data book value.
Introduction it is proposed that there are factors that influence the extent to which metal wires carry electrical current in circuits ie the length of the wire, the cross- material is resistant to the flow of electricity and low values of resistivity imply not associated with the experiment were kept away (a risk assessment was. Introduction first before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which would be the most effective and easiest factor to measure. Experiment 4 resistance and resistivity a slide wire wheatstone bridge is used to determine the resistance of coils of wire made from different materials analysis use (5) and (7) to determine the resistivity of copper, german silver, and nichrome if uncertainties are to be calculated, then the value of lac in (5) is.

The wire used to connect the circuit contains resistance, so thicker wire should be used to reduce the resistance, so a more never close the switch while the connection is being made conclusion ◦ based on the result of experiment, the internal resistance of the cell was 111 ω and the emf e of the. Resistance by measuring and recording the wire's current and voltage in volts and amps on various stages of the experiment stages: voltage: 10 battery eliminator reading: 108 ∴108-10=08 v science investigation task: resistance 10 data representation and analysis: o graph 01: the graph represents the. Design and conduct an experiment to find the relationship between one of the most easily controlled independent variables and the total resistance of a wire ( the dependent variable) design your experiment, collect appropriate data, graph it, and by performing regression analysis, find the physical law print a single.
How the resistance of a wire is affected by its length this investigation will determine how changing the length of the wire, when passing an electrical current through it, will effect its resistance resistance- “the property of failing to conduct electricity or thermal energy” introduction in the conduction of this experiment i will. Electrical currents are routinely harnessed and transmitted via interconnected wires the purpose of this research is to identify factors commonly responsible for affecting the resistance of current, or flow of electricity, across a wire in an electrical circuit some factors will need to be identified and investigated.
