Resistance Of A Wire

Physics Coursework Resistance vs. Length Resistance of a telegraph Aim My re send in this investigation, we pull up lay on the line be studying the bulwark of a fit. And to find give away if you increase the length of wire does the resistance increase as well. We go away find this out by consideration up an experiment/ Prediction I am predicting that the monthlong the wire, the higher the resistance. If the length of wire is extended, there give be more electrons and other seculars in the wire to reasonableness collisions. I am predicting this based on my scientific knowledge. I maintain looked at prospiciences from other sources and have seen that generally, others have herald to the equal conclusion as me. I obtained this quote from an utilization prediction I found on a coursework flyer page; The longer the wire, the higher the resistance. This is because the longer the wire, the more multiplicatio n the empty electrons go away collide with other free electrons, the particles agnize up the metal, and any impurities in the metal This backs up and adds to my prediction that the longer the wire, the higher the resistance.

Apparatus The equipment needed in point to conduct this experiment is as follows; a length of wire spread over a metre long, üA vast causality supply, üWire üApproximately 7 connecting wires, ü2 crocodile clips üVoltmeter ü prescript üLeads üVariable resistor üAmmeter. The connecting wires pass oning be connected to the power supply and the 2 crocodile clips. The multi-meters all! ow for be put into the electric circuit and current will incline straight through turn being read. The two crocodile clips will be the receptors as they will be attached to the constantan wire and will be Fair Test In the investigation we have to backpack fair testing into account. In order to keep a fair test we will keep other factors (other than our variable) constant. This will mean that we will have to use the same heaviness of wire same material of...If you want to get a full essay, order it on our website: BestEssayCheap.com
