What factors affect the resistance of a piece of wire?
What I am going to investigate is, what factors affect the resistance of a piece of wire.
To start this experiment I will need the following equipments:
Power pack
Ammeter
Voltmeter
1 meter ruler (100cm)
110cm of wire
Crocodile clips
This shows how the equipment will be set up.
A
V
I will measure the Voltage and also Current of the wire. Once I have recorded the results I will repeat recording the results 2 more times at 2 more different voltages to make the experiment fair then I will find the average. I will record the Voltage and the Current of the wire in every 10 meters.
I will record my results in a format of a table like this.
Length (cm) Current (I)(amperes) Voltage (V) (volts) Resistance ® (Ohms)
10m
20m
30m
40m
50m
60m
70m
80m
90m
100m
For the Current and the Voltage there will be 3......
