Question

0 4 D 0 2 50 100 150 Temperature T K FIGURE 3 9 esistivity p of er as a function emperature T For listed in Table 3 1 rang would be a straight line At temperatures much lower than 0 C the grap The relation of Eq 3 26 implies that a graph of p plotted against however deviates considerably from a straight line Fig 3 9 Equation 3 26 thus can be used approximately over a limited r of T around any reference temperature To where the graph can approximated as a straight line IMP Resistivity pufcm 1 20 1 10 1 00 200 400 600 800 Temperature T K FIGURE 3 10 Resistivity Pr of nichrome as a function of absolute temperature T P IMP T FIGURE 3 11 Temperature dependen of resistivity for a typic semiconductor
