What combination
(a) For the metals with work functions listed in Table 16.4, what
combination of metals produces the largest contact voltage, and what is its magnitude?
(b) In this couple, which metal is charged positive and which is charged negative?
(a) The contact potential can be calculated with Equation 16.29:
The largest contact potential will result from the largest difference in work functions. From Table 16.4 the greatest work function is 5.6 eV for Pt and the smallest is 1.8 for Cs. The difference in these two work functions produces the greatest contact potential of the materials in Table 16.4.
