In this activity you will use graphite electrodes to try and measure the resistivity of graphite.
You will need
a graphite electrode
multimeter
metal ruler
callipers
Write the relationship for resistance and resistivity
Re-arrange the relationship to make resistivity the subject
What variables do your need to determine resistivity?
What variables will you measure?
Make your measures and calculate the resistivity for graphite.
How does your result compare with others in the class?
How does your result compare with the known resistivity for graphite (you may have to look this up!)
