Resistance of Constantan Wire In this experiment I will be finding out how the resistance of a piece of constantan wire changes depending on its length. Aim: To find out how the resistance of a piece of constantan wire changes with one chosen variable. Possible Variables: * Length: if the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and so more collisions will occur. * Thickness: If the width is increased, the resistance will decrease because there has been an increase of space for the electrons to travel through so there will be fewer collisions of electrons. * Temperature: If the wire is heated up then the resistance will increase because the electrons will vibrate more due to their increase in energy and therefore there will be more collisions. * Type of wire: The type of material will affect...
