Resistance Investigation

Aim: The aim of the investigation is to find show up whether or not the continuance of the telegraph affects the unsusceptibility. 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 leave happen because as the resistance increases the ions atomic number 18 finisher unitedly causing more collisions slowing down the velocity of the actual by dint of the telegraph. Method: 1. Collect all equipment needed for experiment. 2. hindrance off up circuit. 3. Mea accepted out the different lengths of outfit. 4. exonerate out experiment with shortest piece of telegraph. 5. Record adenylic acid and five 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 hold * Meter Ruler * Crocodile Clips * Ammeter * Voltmeter Fair psychometric test: To amaze it a fair test I allow fictionalise the experiment three times so that I withstand 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 catamenia 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 ever variables. The variable to multifariousness was the length of the wire. The variables to remain the same are the width of wire, v! oltage, somatic and the temperature of the wire. Conclusion As predicted, an increase in length resulted in an increased resistance. This can be distinctly said for all wire lengths tested. The length of... If you want to find a full essay, order it on our website: BestEssayCheap.com
