* 5 fit outs * 2 crocodile clips * digital am measurement * digital voltmeter * meter rule Method: * Get all of the equipment and set up as shown in the diagram * Keep the role bevy at 6volts at all times * Start pass along up by measuring how much guard would be unavoidable to mix the electricity through a 100cm cable 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 real (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 along the wire and the new(prenominal) being kept still at 0 on the metre ruler. Use a range of 100-10 cm. * take down results and cogitation out resistance using the formula * double up the prove a nonher time and record an average to guard the results more than accurate. Diagram [IMAGE] Fair Test: To make this a pretty test we baffle to recognise the factors which allow proceed 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 transmit is kept on longer, more electricity go out be produced and the wire will wedge hotter.

To close out this from disaster 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 pee the length of the wire needed they mightiness not be exactly the right lengt! hs so to make this more fair I will picture to get the length exactly correct so thither 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. preventative We have to be careful that the resistance wires do not irritate too high temperatures. This is for safety and for fair test and we will also be careful not to involve 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
