摘要
本文利用非平衡电桥的输出电压与工作臂电阻变化成正比的关系,测出金属导体的电阻温度系数,丰富了物理实验的内容。
By using the relationship that output voltage of unbalanced bridge is in direct proportion to change of working arm resistance,this paper measures the coefficient of resistance temperature of metallic conductor,therefore enriching the contents of physcial experiment.
