Physics Coursework Aim: To find out how changing the length of wire affects its resistance Background Info The standard opinion of resistance when electricity is concerned is the ability of a substance to resist the flow of electricity through it. Good conductors are associated with low resistance and poor conductors are associated with high resistance. As resistance is responsible for the current that flows, a high resistance will be responsible for a low current and a low resistance will be responsible for a higher current. This is definition of resistance given by Hutchinson's Encyclopaedia: "In physics, that property of a conductor that restricts the flow of electricity through it, associated with the conversion of electrical energy to heat; also the magnitude of this property. Resistance depends on many factors, such as the nature of the material, its temperature, dimensions, and thermal properties; degree of impurity; the nature and state of illumination of the surface; and...
