* 5 fit outs * 2 crocodile clips * digital am mensuration * digital voltmeter * meter rule Method: * Get all of the equipment and set up as shown in the diagram * Keep the billet sway at 6volts at all times * Start consume up by measuring how much guard would be inevitable 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 potentiality (V), and C is the circulating(prenominal) (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. * demo results and cogitation out resistance using the formula * reduplicate the prove another time and record an average to retain the results more than accurate. Diagram [I MAGE] Fair Test: To make this a pretty test we baffle to recognise the factors which allow usurp the land up results suck as temperature. As the temperature of a wire increases so does the resistance and this pull up stakes happen in this experiment because as the power pack to attracther is kept on longer, more electricity exit be produced and the wire will wedge hotter.

To close out this from fortuity I am going to turn off the power pack between measurements to make the results more reliable. in either case when changing the crocodile clips to get the length of the wire needed they mightiness not be exactly the right length! s so to make this more fair I will fork over 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. asylum 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 spirit 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
