Method for Investigating Resistance?
Set up the apparatus by connecting two crocodile clips to the thing resistance wire, 10cm apart, and set the power supply to 1.5V
Connect the wire, using the clips, to the rest of the circuit
Record the potential difference from the voltmeter and current from the ammeter
Move the clips in 10cm intervals further apart each item
5) Take the new measurements from the voltmeter and ammeter length reading
6) Continue until the crocodile clips are a meter apart
