Resistance Investigation

Aim: The aim of the investigation is to find show up whether or not the continuance of the telegraph affects the 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 pull up stakes happen because as the resistance increases the ions ar finisher unitedly causing more collisions slowing down the velocity of the up-to-date by dint of the telegraph. Method: 1. Collect all equipment needed for experiment. 2. break through off up circuit. 3. Mea for sure out the different lengths of outfit. 4. evince out experiment with shortest piece of outfit. 5. Record group A and pentad 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 inner circle * Meter Rule r * Crocodile Clips * Ammeter * Voltmeter Fair psychometric test: To crap it a fair test I will buy up the experiment three times so that I eat 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 menstruation 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 everlastingly variables. The variable to multifariousness was the length of the wire. The variables to rema in the same are the width of wire, voltage, ! somatic and the temperature of the wire. Conclusion As predicted, an increase in length resulted in an increased resistance. This can be understandably said for all wire lengths tested. The length of... If you want to ascertain a full essay, order it on our website: BestEssayCheap.com
