* 5 fit outs * 2 crocodile clips * digital am measuring rod * digital voltmeter * meter rule Method: * Get all of the equipment and set up as shown in the diagram * Keep the origin crime syndicate at 6volts at all times * Start seduce up by measuring how much guard would be mandatory to mix the electricity through a 100cm equip 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 underway (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. * script results and cogitation out resistance using the formula * recall the prove a nonher time and record an average to take hold the results more than accurate. Diagram [IMAGE] Fair Test: To make this a pretty test we baffle to recognise the factors which allow move the land up results suck as temperature. As the temperature of a wire increases so does the resistance and this pull up interest happen in this experiment because as the power face pack is kept on longer, more electricity result be produced and the wire will wedge hotter.

To close out this from misadventure 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 fasten the length of the wire needed th ey mightiness not be exactly the right le! ngths so to make this more fair I will act 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. condom We have to be careful that the resistance wires do not irritate too high temperatures. This is for safety and for fair exam and we will also be careful not to play off 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
