What affects the resistance of a piece of wire-Analysis

Extracts from this document...

Introduction

What affects the resistance of a piece of wire-Analysis As I was collecting my data I noticed a pattern straight away. As the length of wire increased the current getting through the resisting wire was decreasing- (The resistance was increasing.) When the wire was 10cm long the resistance was 0.4484 and when the wire was 20cm long the resistance was 0.8929. ...read more.

Middle

The first graph showed a curved line -meaning that the length of the wire is not proportional to the amps. But the second graph was a straight line showing that the length of the wire is proportional to the resistance so the second part of my prediction was also correct. ...read more.

Conclusion

to collide with. Each time the electrons collide with the atoms of material they lose some of their energy so by the time they come out the other side of the resistor they only have half of their original energy This means that double the voltage is needed to push through the same amount of current. And as the same voltage is being used each time not as much current is being pushed through. ...read more.
