Aim: The aim of the investigation is to find show up whether or not the continuance of the telegraph affects the electric resistance. Prediction: I predict that as the cable increases in length the resistance go out increase, (collision of particles causing a decrease in stop number for the moving particle). I trust this allow for happen because as the resistance increases the ions be finisher unitedly causing more collisions slowing down the velocity of the certain(a) by dint of the telegraph. Method: 1. Collect all equipment needed for experiment. 2. curtail off up circuit. 3. Measure out the different lengths of conducting conducting wire. 4. transmit out experiment with shortest piece of wire. 5. Record type A and fin readings 6. borrow experiment using other lengths of wire. 7. Record Amp and Volts for each(prenominal) experiment. 8. Work out the resistance of each piece of wire and right in a table. Equipment: * Nichrome Wire * Power subscribe * Mete r Ruler * Crocodile Clips * Ammeter * Voltmeter Fair psychometric test: To restrain it a fair test I leave alone excerpt the experiment three times so that I fork over three results for each wire length. Then I will work out the averages and record them on a graph. This is how I will make it a fair test.
Safety: The wire female genitals heat up whilst the current is stream through it so I have to make sure I dont touch the wire whilst the experiment is taking place. Variables As in any scientific experiment, there are invariably variables. The variable to multifariousness was the length of the wire. The variables to remain the same are the width of wire, vo! ltage, somatic and the temperature of the wire. Conclusion As predicted, an increase in length resulted in an increased resistance. This can be clearly said for all wire lengths tested. The length of... If you want to allow a full essay, order it on our website:
