Hi, I was just really stuck on this wjec AS past paper ques, would appreciate it if anyone could help me.
Qi) Draw a labelled diagram of the apparatus you could use to determine the realtionship between the resistance and length of wire.
(ii) what further measurements would you need to make to determine the resistivity of the metal and what apparatus would you use to make your measurement?
(iv) Explain how a value of the resistivity is determined from your measurements.
Thanks for your time.
