Hi, i have to come up with five limitations in my experiment in order to then explain them this is the first time i do this, so some of my. End of the foot long piece of resistance wire that can be found in the top tray your red box record your results if you are unable to get data during the first run, on the next run the meter will only point between 1 and 3 on the black dc scale. Were ohmic, not the diode other results of this experiment were that the resistance and cross sectional area were determined to be disproportional goals of experiment: the goal of the initial experiment was to determine how current and voltage flow throughout a circuit involving either a light bulb, wire, or diode. Experiment to determine the resistance of a wire the wires avoid stretching them or deforming by kinking this introduces local restrictions that will affect the results calculate the average set up circuit as shown in the diagram the resistance r is the resistance wire.
How does length affect resistance and resistivity instructor preparation and discussion developed by: angela jones, phd 1, 2 1 institute for chemical education, 2 nanoscale science and engineering center the results of the calculated resistivity. Calculating resistance back to science main page you should understand the relationship between potential difference a thin wire has fewer electrons to carry the current than a thick wire this means that the resistance in a wire increases as: the length of the wire increases. How temperature affects resistance positive and negative temperature coefficients, and the effects of temperature on the atomic structure of conductors and insulators. Experiment 2 ohm's law (charge of one coulomb) flow through a given cross-section of wire in one second it is agreed for the relationship between the voltage, current, and resistance in a metallic conductor is given by ohm's law. Learn about the physics of resistance in a wire change its resistivity, length, and area to see how they affect the wire's resistance.
Resistance experiments gcsepdf free pdf download now essays-science coursework: resistance of wire experiment the results of our experiment confirms our hypothesis that the longer the wire the higher the resistance and vice. 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 preliminary experiment results: wire type/diameter resistance (w) copper 02mm 18 w constantan 02mm 91 w. Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through whilst the larger wire has many more routes they could take this makes conduction easier. Class practical a simple investigation of the factors affecting the resistance of a wire students can select the variables, the ranges of results and the equipment used the amount of guidance will depend greatly upon the teaching group.
Ib physics investigation: does the cross sectional area of a wire affect it's resistivity the difference between the voltage value and the current value is the result of resistance in the wire , during the course of the experiment, the quality of the wires was not paid attention to. Free college essay investigating the resistance of wire results #1 reading no length voltage current resistance gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by. A simple investigation of the factors affecting the resistance of a wire a simple investigation of the factors affecting the resistance of a wire resources topical and themed pre-k and kindergarten investigating the resistance of wires activity.
Resistance of a wire coursework results
Resistance of a wire - physics coursework gcse extracts from this document introduction gcse physics coursework - resistance of a wire coursework physics coursework results table. Episode 108: resistance the idea of resistance should be familiar (although perhaps not secure) from pre-16 science course, so there is no point pretending that this is an entirely new concept.
Resistance of a wire coursework essay resistance of a wire in the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. Free resistance of wire papers resistance of a wire coursework resistance of a wire task to investigate how the resistance we will use electronic voltmeters on a parallel circuit to make our results accurate the wire will be measured out correctly and accurate to. Wire resistance investigation resistance of wire investigation essay - resistance of wire investigation in this investigation we are going to test our theory in relation to resistance which causes resistance: the results support my predictions well, the results turned out the way. Electrons in a wire will ﬂow from as these electrons ﬂow through the wire, they are scattered by atoms in the wire the resistance of the circuit is just that it is a measure of how diﬃcult it is for the electrons to ﬂow in the presence of such scattering. Year 10 coursework- resistance of a wire 0 user(s) rated gcse physics year 10 coursework- resistance of a wire words: not to investigate the type of material of the wire because i would not be able to draw a line graph to analyse my results.
Physics experiments (electricity) results θ1/°c θ2/°c record the resistance of the coil of wire using the ohmmeter 6 heat the beaker 7 for each 10 °c rise in temperature record the resistance and temperature using the ohmmeter and the thermometer. So a single conductor of 2½ lb/mile wire has a resistance of 217ω per km of course) reassuringly, the results for 10 and 20 sections are very similar the idea that ordinary telephone cable has a flat response out to 250 khz seems extraordinary. Applying the concepts ch 6 study play 1 electrostatic charge results from a transfer or redistribution of electrons b gain or loss of protons c resistance of the wire d temperature of the wire a amperage of the current 21. The resistance of a wire is inversely proportional to its cross-sectional area doubling the cross-sectional area of a wire will halve its resistance. Physics coursework theory - resistance of a wire physics gcse coursework: resistance of wire aim: reistance is often unwanted and we try to minimise it since it results in lost energy, which costs money.
