电线和电流为第增关系。电线的线径越大所能承载的电流也就越多， 电线的大小和所能承载的电流的多少成正比关系。电流=功率/电压电流和也是成功率正比关系。所以电线的线径越大所能承载的功率也就越大， 电线的大小和所dian ji ding zi tong xian cu xi ，dui dian ji ding zi dian liu ji gong lv you ying xiang 。1 、ying xiang dian liu ding zi dian liu I = U / Z Z shi xian quan de zu kang ，Z = √ （X ² + R ² ）X shi xian quan de gan kang ，R shi xian quan de dian zu R = ρ L / S S shi "

其实线径与电流原本没有直接关系，因为电流大了导线发热，绝缘层会损坏，与绝缘层的耐热、环境的散热条件相关。所以我们在选择导线或对PCB布线时，一定要要注意根据电流选择合适的线径(线宽),以免发热量过大造成危险绕组线径是指电机绕组中使用的导线的直径，它对于电机的性能有着重要影响。绕组线径较细时，电阻值相对较大。反之，线径较粗时，电阻值相对较小。由欧姆定律可知，电流等于电压除以电阻，即I=U/R,当电压不变而阻值减小时，电流必然增大。
