Discovery of the error and repair it.

Today we had meeting our supervisors Dr.Yan to discuss our project.In the meeting at first Dr.Yan say our figure is good, but after our analysis, we find we had some error in our project, there is maybe our result is wrong. The expected and actual value is contrary. We try to back lab and had new circuit to apply our project. After we finished that we visit Dr.Yan he say this figure is right and perfect. He ask us do more and more detailed figure in the different resistance. But in the end of day, we can not make more detailed, and we do not know why. We would try in the next time.
