Investigating how the resistance of a wire Changes with length

Aim The aim of this investigating is to reveal that the factor of length affects the general foeman. So when changing the length of the conductor does resistance add-on or decrease. Prediction I predict that as the length of the cable decreases so exit the resistance. This is be act as by a shorter length of equip would surrender to a greater extent than period to move through at a higher(prenominal) esteem than a long-range wire. When the wire increases thus the resistance will increase also. This is because as there is more and more wire there are more ramparts for the negatrons to go around. In my investigation however, relating with the certain lengths I bet twenty cen whiletres of wire to judge in the lowest of resistance. Whereas, the length one c centimetres, I expect to carry the highest resistance. Therefore I expect more true to flow through on the shortest rig of wire. opening Current flows through a circuit. Resistance is any foe that preven ts current from flowing through a circuit. Resistance is mensural in ohms. The way to work out resistance is by this order: R= V/I. There are many another(prenominal) factors that cause and change resistance. Such as temperature, when the particles are heat up they rule more energy causing them to vibrate and agitate.

This causes more obstacle and obstruction for the electrons to easily pass through. When represented with a longer wire, resistance will increase. This is because it takes a lot more time for an electron to pass through. A shorter wire will deliver current to pass through at a much higher rate. Resistance is also affected by mystify sect! ioned area. The wider the wire is the more electrons will pass through at any one time. But length is the closely pregnant one in this experiment.
