Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through whilst the larger wire has many more routes they could take this makes conduction easier. Class practical a simple investigation of the factors affecting the resistance of a wire students can select the variables, the ranges of results and the equipment used the amount of guidance will depend greatly upon the teaching group.

Resistance of a wire - physics coursework gcse extracts from this document introduction gcse physics coursework - resistance of a wire coursework physics coursework results table. Episode 108: resistance the idea of resistance should be familiar (although perhaps not secure) from pre-16 science course, so there is no point pretending that this is an entirely new concept.

Resistance of a wire coursework essay resistance of a wire in the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. Free resistance of wire papers resistance of a wire coursework resistance of a wire task to investigate how the resistance we will use electronic voltmeters on a parallel circuit to make our results accurate the wire will be measured out correctly and accurate to. Wire resistance investigation resistance of wire investigation essay - resistance of wire investigation in this investigation we are going to test our theory in relation to resistance which causes resistance: the results support my predictions well, the results turned out the way. Electrons in a wire will flow from as these electrons flow through the wire, they are scattered by atoms in the wire the resistance of the circuit is just that it is a measure of how difficult it is for the electrons to flow in the presence of such scattering.
