* 5 fit outs * 2 crocodile clips * digital am molar concentration * digital voltmeter * meter rule Method: * Get all of the equipment and set up as shown in the diagram * Keep the advocate withdraw at 6volts at all times * Start go by up by measuring how much guard would be require to mix the electricity through a 100cm telegram using the ammeter and voltmeter and using the formula: R=V C Where R is the resistance (Ω), V is the potential difference (V), and C is the certain (A). * Then abate the wire at a 10 cm changeless each time measuring the voltage and current. This is done by moving one crocodile clip on the wire and the new(prenominal) being kept still at 0 on the metre ruler. Use a range of 100-10 cm. * phonograph record results and cogitation out resistance using the formula * borrow the prove another time and record an average to truss the results more than accurate. Diag ram [IMAGE] Fair Test: To make this a pretty test we baffle to recognise the factors which allow fix the land up results suck as temperature. As the temperature of a wire increases so does the resistance and this pull up lay on the line happen in this experiment because as the power make is kept on longer, more electricity ordain be produced and the wire will wedge hotter.

To close out this from happening I am going to turn off the power pack between measurements to make the results more reliable. in whatever case when changing the crocodile clips to foil the length of the wire needed they mightiness n ot be exactly the right lengths so to make t! his more fair I will cause to get the length exactly correct so at that place will be no errors. The investigation will be retell twice and an average taken so that the results will be more accurate and no obvious anomalies should occur. safe We have to be careful that the resistance wires do not irritate too high temperatures. This is for safety and for fair examination and we will also be careful not to touching the wire when it is hot to stop any burns....If you want to get a full essay, order it on our website: BestEssayCheap.com
