In fact, the thermal energy will on

In fact, the thermal energy will only increase the intensity of the random motion of the particles within the material and make it increasingly difficult for a general drift of electrons in any one direction to be established. The result is that
for good conductors, an increase in temperature will result in an increase in the resistance level. Consequently, conductors have a positive temperature coefficient.
The plot of Fig. 3.13(a) has a positive temperature coefficient.

事实上，热能源将只增加强度的材料内颗粒的随机运动并使其日益电子一般漂移的陈设在任何一个方向，建立。其结果是，对于良导体，温度升高将导致增加的阻力位。因此，导体具有正的温度系数。图 3.13(a) 的情节具有正的温度系数。

事实上，热能只会增加粒子的随机运动的强度在材料和使它越来越差fi邪教一般漂移在任何一个方向是建立电子。结果表明
良好的导体，温度的增加会导致在抗性水平的增加。因此，导体具有正温度系数ficient。
图3.13的图（一）具有正温度系数fi
有效。
