I'm in 8th grade, been studying electronics for 2 months, and decided to do a physics based project. I want to know how temperature affects the resistance of a wire, and this is my plan. I would like constructive criticism.
3 1.5 volt batteries in a battery case will be connected to 1 meter of copper wire that will all be connected to a multimeter where I will have it measure ohms.
However, there are still some concepts I need help understanding. one website recommended to wrap the wire with insulation tape around a PVC pipe (i don't know what a PVC pipe is). It also said to use jumper wires with crocodile clips for connection.
It also said to use an infrared thermometer and a paper knife for stripping a wire (which I don't get). I am fairly new to science experiments and this is my second hands on experiment.
