How could you use your open circuit to test if a material is a conductor or insulator?
I'm thinking that you would have to use the resistance of a light bulb. If you set it all up, and the light bulb did not turn o, you have an insulator, if it did turn on, you have a conductor. I'm not sure... Is it right? If not, what's the answer? Thanks in advance!!!

I do not know what your open circuit looks like but your suggestion seems reasonable.
