﻿The effect of Length on the overall resistance of a circuit. Research question:
How does the length of the conductive putty affect the over all resistance of a circuit? This experiment will be discussing how the length of the conductive putty wire affects the overall resistance of a circuit. The variables for this experiment are being used for a number of reasons, however one of the main reasons behind choosing this experiment is investing how length of an object is affected be the resistance. The electrons move away from the individual atoms of the wire when there is a electricity flow. This will cause a decrease in the speed at which the electrons move which then in matter of time, the electrons eventually stop. When electrons move through a conductor, electricity flows, which illustrates the moving of electrons in the wire which collide with the ions in the metal. This then makes it more difficult for the current to flow, causing more resistance. When these electrons move they create an electric current. The electric current being measured from different lengths of wires is what this experiment is conducted by.  Hypothesis:

The hypothesis for this experiment is this: as the length of the conductive putty wire increases, the amount of resistance will also increase. In other words, as the length of the conductive putty wire shortens the amount of resistance will also decrease. The reason behind choosing this hypothesis is that the resistance of a longer wire will face more resistance than the resistance of a shorter wire. The larger the resistance, the greater force will be applied and more energy will be used to have a flow in the current. Another reason justifying the prediction is that the electricity will flow through wider wires of the putty at a higher rate as compared to a narrower wire. In other words, in a longer piece of wire, more atoms would be there for the electros to collide with which would result in the resistance being greater. The...
