Physics Investigation;
Testing Resistances
Jack Burnham 10C (2001)
Planning;
The Investigation:
My investigation will aim to show how the resistance of a wire is altered with the length of the wire.
Equipment List:
For the experiment I will need;
An Multi-meter / Ohmmeter,
A large amount of "Constantan wire",
Normal Wire,
2 Crocodile clips,
Some Cardboard,
A Ruler,
A Wire-cutter.
Prediction:
I think that the length of the wire will affect the resistance. My prediction is that the longer the wire, the higher the resistance, this is also what Encarta online encyclopaedia thinks. (http://encarta.msn.com/)
