How The Lenght Of a Wire Affects Its Resistrence

aHow the Length of a Wire Affects its Resistance In this probe I am going to measure how the continuance of a fit locomotes its bulwark. However there early(a) factors which affects the guard of a cable. These atomic number 18: 1) Cross sectional area- If you decrease the thickness (the cross-sectional area) of a telegraph you ontogeny its resistance be social movement it has a little space for the atoms and electrons to shake up meaning there is a high resistance. 2) Temperature- In a metal conductor, its resistance regulate increase with temperature, because as the current flows through the resistance of the wire heats up. This is because the excess electrons jar with the atoms as they pass through the wire. As the electrons collide with the atoms, they pass their energy on to the atoms causing them to tickle to a greater extent and faster. The faster the vibrations are the high the temperature leave behind be. 3) Material- Metal condu ctors collapse more resistance than insulators as the metals consume free electrons which take up of the atoms causing them to waver more passing the energy on faster. I account that as I increase the length of the wire, the resistance leave also increase thence the length is directionally proportional to the resistance.

So if I double the length of a wire the resistance leave alone also double. I announce this because the longer the wire is, the more atoms there are and therefore the electrons will collide with more atoms creating greater resistance. So the more atoms will cause more opposition therefore increase the resistanc e. I predict that the shortest piece of wire! will have the least resistance and the longest piece of wire will have the superlative resistance. During this investigation my controlled variable quantitys will be the other factors which affect resistance: Cross-sectional area, temperature and the material of the wire. My independent variable will be the length of the wire as I will change the length six times. The dependent variable is the resistance...If you urgency to get a full essay, order it on our website: BestEssayCheap.com
