Plan for Science Course Work The Resistance of Lengths of Wire
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.
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…
