为什么鸟儿停在电线上不会触电?
鸟儿停在电线上不会触电主要是因为鸟儿只接触一根电线、鸟儿的电阻很大以及鸟儿干燥的脚爪，具体如下：
1、鸟儿只接触一根电线：触电的原理是形成回路，有电流通过身体。鸟儿站在一根电线上时，只接触到了一个电位，没有形成电位差，因此不会有电流流过身体，也就不会触电。
2、鸟儿的电阻很大：鸟儿的身体电阻相对较大，即使同时接触到两根电位不同的电线，由于电阻大，流过身体的电流也非常小，不足以对身体造成伤害。
3、鸟儿干燥的脚爪：鸟儿的脚爪通常保持干燥，干燥的脚爪具有很好的绝缘性能，进一步阻止了电流的流过。
总结：鸟儿停在电线上不会触电主要是因为鸟儿只接触一根电线、鸟儿的电阻很大以及鸟儿干燥的脚爪。
