Resistance Of A Wire

The resistance of a wire

Planning:-

Introduction:
To investigate the resistance of a wire at different lengths to see whether or not a longer wire has a larger resistance than a shorter wire.

Apparatus:
Wire
Voltmeter
Ammeter
Battery
2 crocodile clips
Metre rule
Variable resistor

Diagram:

Variables:
Length
Thickness
Resistance
Material

The material and diameter of the wire needs to be kept constant to keep the test fair as we are investigating resistance. The independent variable will be the length of wire as we will be changing it to see whether or not the resistance changes. The dependent variable will be the resistance of the wire as that is what is going to change due to the length of wire.

The length of wire will be measured accurately using a metre rule. The wire will be stuck onto the rule using tape. This means that the wire will not move about so we can measure the length accurately. Repeating measurements improve accuracy as you can......
