26 milli ampers of current
the resistense would vary from person to person. but avg
value of the resistence is 1000OHMs

Answer / shaul hamid

The perception of electric shock can be different depending
on the voltage, duration, current, path taken, frequency,
etc. Current entering the hand has a threshold of perception
of about 5 to 10 milliamperes (mA) for DC and about 1 to 10
mA for AC at 60 Hz. Shock perception declines with
increasing frequency, ultimately disappearing at frequencies
above 15-20 kHz.

Answer / p pichumani

The threshhold value of current than can make a person numb
is 27 milli amps. In my opinion the resistance would vary
from person to person

The knee point of a current transformer is normally unique and known.So why in the nameplate of a CT they put the minimum value like this Vk> 400v.
