An Investigation into a Factor Which Affects the Resistance of a Piece of Wire Skill P Planning Introduction The resistance of a piece of wire is the determined by the speed that an electrical current can pass through it. Every object that conducts electricity has resistance as no object have no resistance, although some do have very low resistances. This is due to the fact that many different factors affect the resistance. Key Factors The possible factors I can investigate are:- * Diameter * Length * Temperature * Material I shall Investigate Diameter as it is the easiest to get good results with. Research Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors. A current is the amount of charge that goes through any particular part of the wire at any particular time caused by the movement of electrons, although it is usually measured in coulombs, which is 'electrons...
