Passage II

Resistivity is the tendency of a material to oppose the flow of an electric current, whereas conductivity is the ability of a material to carry an electric current. Table 1 lists, for each of 12 metals at the same temperature, the density (in grams per cubic centimeter, g/cm3), resistivity (in ohm meters, Ω∙m), and conductivity (in siemens per meter, S/m). Figure 1 shows, for 3 of these metals, how resistivity varies with temperature (in kelvins, K).

9. Based on Table 1, of the following 4 metals, which has the greatest ability to carry electric current?

Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

Look at the second line of the first paragraph of the article whereas conductivity is the ability of a material to carry an electric current, so you only need to compare the four materials among the options and which one has the highest conductivity. It can be seen that Beryllium has the largest conductivity and the best conductivity
