        Current path through body. The current path is also important because of the organs that may be affected. For example, a hand-hand path, as shown in Fig. 1, causes the current to pass directly through the heart. A left hand-left foot path, as shown in Fig. 2 (on page 38), again causes the current to pass through the heart. A right hand-right foot path, as shown in Fig. 3 (on page 38), or hand to elbow path is not quite so critical. A foot-foot path, as shown in Fig. 4 (on page 38), results in current passing through organs that are vitally important.

        If electricity enters your body through your left hand, it's probably going to try to exit into the ground through your left foot, passing right through your heart along the way.

[3] Tubelab, Safety — Electrical Safety

        Electric current that passes through the chest area is capable of causing death due to asphyxiation or cardiac arrest. With this in mind you must not put yourself in a situation where current could pass from hand to hand or hand to foot. The path of left hand to right foot is the worst case. This is why many texts will tell you to work with one hand in your pocket.

A, the shortest going through heart with the resistance the least?

现在回忆见到的那位电工大概是右脚腕子上的出来的洞,推测是左手触摸的。可能他是被高压电打到了,只听说。

按杨老师的选择项应该是E。
一般来说最危险的是电流通过神经密集的身体组织和器官,相比起来手触电是最不危险的。以前在工厂劳动我师傅教我说,看线上有电没电要用手指背去敲一下,有电就会弹回来,千万不可去摸,那样你就会抓上去.....。细想就是手很灵敏,如果头、后脊碰到电可能就反应不及,电流又通过神经路径,开挂可能性很高吧?你看电工都要戴绝缘安全帽。
回复  (1)从左手到右脚;
(2)用手指背去敲一下,有电就会弹回来,
千万不可去摸,那样你就会抓上去。

关键看实际流过人体的电流和持续的时间吧。
回复  现在是打听“最危险的路径”。

最安全的是尽可能远离。别去碰它

没研究,印象中好像是过心脏,另外,电压越高,越危险,比通过哪里更重要

不懂物理学,猜一个A。如果都带着绝缘的手套或者胶鞋也会被电到?弄不懂。被点击之后的伤口是很难愈合,溃烂化脓。尤其是腿部脚腕子以上的地方能烂一个洞。见过这样一位活到80多岁,曾是个电工出了工商直到老死40多年都长不上。生肌散都治不了,很可怕。
