Can lee's experiment be done with a good conductor?

Answer 1

That depends entirely on which "Lee" is being referred to and what his or her experiment consisted of.

One possibility is that you are referring to the determination of the thermal conductivity of a poor conductor using a thin disk of the material between two brass disks (Lee's Disc Method). In the original experiment, one of the fundamental assumptions is that the disk is a poor conductor and thus that heat losses through the edges of the disk are negligible - but if the conductor is a good one, this assumption may not be valid and will introduce an indeterminate error into the calculations. It will also cause variable results depending on what external temperature the disk is discharging to (or absorbing from if the surroundings happened to be particularly hot.) For this reason, other methods are recommended for measuring thermal conductivities of good conductors such as Searle's Bar Method.

Answer 2

Lee's experiment, which involves passing electric current through a resistive material to generate heat, may not be effective with a good conductor since conductors have low resistance and therefore generate less heat when current flows through them. For the experiment to work as intended, it is important to use a material with higher resistance to produce sufficient heat for the demonstration.
