Essay's paper body
After connecting everything as the diagram shows, we turned on the power pack so that a flow of electrons could be sent around the circuit. I set the variable resistor so that the readings on the voltmeter and ammeter wouldn't run off the numbers shown. Then, I recorded the readings on the voltmeter and ammeter...

Then, I recorded the readings on the voltmeter and ammeter. Since the voltmeter was set to 3 volts, those recordings were all the same. To work out the resistance, I divided the readings on the ammeter by the readings on the voltmeter for each length.
First I shall set up the circuit (see image 1). Then I shall start of with a wire which has a length of 100 cm and read the volts and current by looking at the volt + ammeter, with that information I shall use the equation from Ohm's law to figure out the resistance...
