Aim:
To investigate the resistance of different lengths of wire and to look for a correlation between the length of the wire and it's resistance.
Research:
Ohm is the common unit of electrical resistance, equivalent to one volt per ampere and represented by the capital Greek letter omega. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature. When cooled to extremely l…
