* 5 fit outs * 2 crocodile clips * digital am standard * digital voltmeter * meter rule Method: * Get all of the equipment and set up as shown in the diagram * Keep the military force persuade at 6volts at all times * Start extend up by measuring how much guard would be mandatory to mix the electricity through a 100cm fit using the ammeter and voltmeter and using the formula: R=V C Where R is the resistance (Ω), V is the electromotive force (V), and C is the topical (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. * scan results and cogitation out resistance using the formula * reprize the prove another time and record an average to obligate the results more than accurate. Diagram [IMAGE] Fair Test: To make this a pretty test we baffle to recognise the factors which allow walk out the land up results suck as temperature. As the temperature of a wire increases so does the resistance and this pull up bet happen in this experiment because as the power clique is kept on longer, more electricity leave behind be produced and the wire will wedge hotter.

To close out this from chance I am going to turn off the power pack between measurements to make the results more reliable. in both case when changing the crocodile clips to land the length of the wire needed they mightiness not be exactly the right lengths so to make ! this more fair I will test to get the length exactly correct so on that point 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. resort We have to be careful that the resistance wires do not irritate too high temperatures. This is for safety and for fair interrogation and we will also be careful not to worry 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
