Plan for resistance of wire

Investigation to determine how the resistance of a wire is affected by changing its length and thickness.

Plan-

Circuit diagram of the apparatus, as it will be set out:



















How I will collect my results:

1. Firstly I will collect and assemble apparatus as shown above.
2. I will then position the length and thickness of wire that I have planned to do into the circuit, at the precise points along the wire, I will record my results.
3. I will repeat this process for different wire thicknesses.
4. I have planned to run a current of 0.1A through the circuit and record all the results and I will also run a current of 0.2A through the circuit and record them as well.

Repeating measurements and anomalous results:

I will repeat all of my readings twice although this will not show on my results tables. I will take one reading and then if the second reading is not within 0.2volts of each other. If I get any anomalous res...
