Resistance of a Wire
The resistance of a wire
Aim: The resistance of a wire depends on certain factors. Investigate the effect of two of these factors ¡V
Planning
Some variables that will be relevant to this investigation are:
„h Length
„h Thickness
„h Temperature
„h Voltage
„h Resistance
„h Material
Of these the variables will be input and output voltages in experiment one, and length and resistance in experiment two. The other variables (temperature, material and voltage) will …showed first 75 words of 1665 total…

…showed last 75 words of 1665 total…R halves. for example when the Area is 0.025mm2 the resistance is 4.8. When A doubles to 0.05, R halves to 2.4?. When A doubles again, R halves again to 1.2. This is because, as stated earlier: We see that if the area of the wire doubles, so does the number of possible routes for the current to flow down, therefore the energy is twice as spread out, so resistance might halve, i.e. Resistance is directly proportional 1/Area.
