Why are we not crossed by a current in our body? Consider a person with 1.8m height: he should be crossed by, if for instance we consider a mean value of human body resistance equal to 10kOhm, 180V/10kOhm = 18mA of current, that is quite high for human body. We will surely perceive it, since it is similar to that we perceive if we touch the phase of our home electric network.
