A)Why is the electrical resistivity of a thin film metal higher than its bulk value? Choose one.

- a) It experiences excessive surface oxidation - b) It has a lower work function - c) Dimensions of the film are comparable to the mean free path

- d) a and b - e) b and c - f) a and b and c

B) Describe how electrical conduction occurs in a lithium polymer electrode?

C) Describe thermal conduction in metals and how it differs from thermal conduction in an insulator. d) What is drift mobility? If we have conduction by ion diffusion in an insulator, is the drift mobility large or small compared to that of a metal? Why?

D) What is drift mobility? If we have electrical conduction by ion diffusion in an insulator or polymeric system, is the drift mobility large or small compared to that of a metal? Why?
