Study Guide- Chapter 10 Compare resistance to resistivity. How does conductivity relate to resistivity? Identify the parameters in the conductivity equation and show how the various parameters are affected by the type of material (conductor, semiconductor, and insulator), temperature, purity, and defect concentration. What is the temperature coefficient of resistivity? Know how to sketch and interpret the band structure for a conductor, semiconductor and insulator. ( 29 i i i i N q σ μ =

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
